                                 REPRESENTATIONS

     Section  2.01.  REPRESENTATIONS  BY ISSUER.  The Issuer makes the following
representations as the basis for the undertakings on its part herein contained:

     (a) The Issuer is a governmental  agency, body politic and corporate of the
State of Texas,  existing as a conservation and reclamation district pursuant to
the Issuer Act, and a "river  authority" and an "issuer"  within the definitions
set forth in the Acts.

     (b) The  Issuer  has the  legal  power  under  the Acts to  enter  into the
transactions  contemplated  by  this  Agreement,  the  Indenture  and  the  Bond
Resolution and to carry out its obligations hereunder and thereunder,  including
the  issuance  and  delivery  of the Bonds,  and to adopt and  perform  the Bond
Resolution; and each such instrument is a legal, valid and binding obligation of
the Issuer  enforceable in accordance with its terms,  except to the extent that
the  enforcement   thereof  may  be  limited  by  (i)  bankruptcy,   insolvency,
reorganization, moratorium, or other laws now or hereafter in effect relating to
or affecting creditors' rights generally,  and (ii) general principles of equity
(regardless of whether enforceability is considered in a proceeding at law or in
equity). The Issuer has been duly authorized to execute, deliver and perform its
obligations under this Agreement and the Indenture, and to adopt and perform the
Bond Resolution by proper action of the Board.

     (c)  The  Issuer   officially   finds  and  determines  that  each  Project
constitutes "control facilities" within the meaning of Chapter 383 and "disposal
systems"  within the  meaning of  Chapter 30 and a "public  utility"  within the
meaning of Article 717q.

     (d) The  Issuer,  by carrying  out the  purposes of the Acts as provided in
this Agreement,  will be performing an essential public function under the Texas
Constitution.

     (e) The Issuer is not in default under any of the provisions of the laws of
the State which would impair,  interfere with, or otherwise adversely affect the
ability of the Issuer to make and perform the provisions of this Agreement,  the
Indenture, or the Bonds.

     (f) There are no actions, suits,  proceedings,  inquiries or investigations
pending or to the knowledge of the Issuer  threatened,  against or affecting the
Issuer in any court or before any governmental authority or arbitration board or
tribunal,  which involve the  possibility of materially and adversely  affecting
the  transactions  contemplated  by this Agreement or the Indenture or which, in
any way, would adversely affect the validity or enforceability of the Bonds, the
Indenture  or this  Agreement  or the  ability  of the  Issuer  to  perform  its
obligations under the Indenture or this Agreement.

     (g) The adoption of the Bond Resolution, the issuance and sale of the Bonds
and  the  execution  and  delivery  by the  Issuer  of  this  Agreement  and the
Indenture,  and the  compliance by the Issuer with all of the provisions of each
thereof and of the Bonds (i) are within the powers and  authority of the Issuer,
(ii) have been done in full  compliance  with the  provisions  of the Acts,  are
legal  and will not  conflict  with or  constitute  on the part of the  Issuer a
violation of or a breach of or default  under,  or result in the creation of any
lien,  charge or  encumbrance  upon any  property  of the Issuer  (other than as
contemplated  by this Agreement and the Indenture)  under the provisions of, any
charter instrument,  by-law, indenture,  mortgage, deed of trust, note agreement
or other  agreement or instrument to which the Issuer is a party or by which the
Issuer is bound, or any license,  judgment, decree, law, statute, order, rule or
regulation of any court or governmental  agency or body having jurisdiction over
the  Issuer or any of its  activities  or  properties,  and (iii) have been duly
authorized by all necessary action on the part of the Issuer.

     (h)  Neither  the  nature  of the  Issuer  nor  any of  its  activities  or
properties,  nor any relationship  between the Issuer and any other person,  nor
any circumstance in connection with the offer, issue, sale or delivery of any of
the Bonds is such as to require the consent,  approval or  authorization  of, or
the filing,  registration or qualification  with, any governmental  authority on
the  part  of  the  Issuer  in  connection  with  the  execution,  delivery  and
performance  of this  Agreement and the Indenture or the offer,  issue,  sale or
delivery of the Bonds, other than those already obtained as of the date of issue
of the  Bonds;  provided,  however,  no  representation  is  made  herein  as to
compliance with the securities or "blue sky" laws of any jurisdiction.

     (i) No event has  occurred  and no  condition  exists  with  respect to the
Issuer  which would  constitute  an "Event of Default"  under this  Agreement or
under  the  Indenture  or which,  with the  lapse of time or with the  giving of
notice or both, would become an "Event of Default" under this Agreement or under
the Indenture.

     (j) Neither this  Agreement nor the security for the Bonds has been pledged
or  hypothecated  in any manner or for any purpose other than as provided in the
Indenture as security for the payment of the Bonds.

     (b) Neither the execution and delivery by WTU, PSO or CPL of this Agreement
nor the consummation by WTU, PSO or CPL of the transactions contemplated by this
Agreement  conflicts  with,  will result in a breach of or default under or will
result in the imposition of any  prohibited  lien on any property of WTU, PSO or
CPL, as the case may be,  pursuant to the  corporate  charter or by-laws of WTU,
PSO or CPL, as the case may be, or the terms,  conditions  or  provisions of any
statute,  order, rule, regulation,  agreement or instrument to which WTU, PSO or
CPL, as the case may be, is a party or by which it is bound.

     (c) This Agreement has been duly authorized, executed and delivered by each
of WTU, PSO and CPL and constitutes the legal,  valid and binding  obligation of
each of them enforceable in accordance with its terms, except to the extent that
the  enforcement   thereof  may  be  limited  by  (i)  bankruptcy,   insolvency,
reorganization, moratorium, or other laws now or hereafter in effect relating to
or affecting creditors' rights generally,  and (ii) general principles of equity
(regardless of whether enforceability is considered in a proceeding at law or in
equity).

     (d)  There is no  material  litigation  or  proceeding  pending,  or to the
knowledge of any of WTU, PSO or CPL  threatened,  against any of WTU, PSO or CPL
which could  reasonably  be expected  to have a material  adverse  effect on the
validity of this  Agreement  or the ability of any of WTU,  PSO or CPL to comply
with its obligations under this Agreement.

     (g) All statements of facts or other  information  furnished by the Company
to Bond Counsel in connection with Bond Counsel's opinion relating to the Bonds,
including  particularly the Tax Letter of Representation,  were true and correct
in all  material  respects  when  made and  nothing  has  come to the  Company's
attention that would change the truth or correctness of such statements of facts
or other  information  furnished to Bond Counsel.  Moreover,  to the extent that
such representations and statements relate to future events, the Company agrees,
at all times while the Bonds are Outstanding, to take such action to prevent, or
to refrain  from any action  which  would  result in, such  representations  and
statements becoming false, inaccurate or incorrect.

     (h) The  representations  of the Company stated in the Prior Agreement were
true and correct  when made and nothing has come to the  Company's  attention to
make such representations untrue as of the date hereof.

portion of the Project after the Company shall deem in its discretion  that such
continued  operation is not advisable and in such event it is not  prohibited by
this Agreement from selling,  leasing or retiring all or any such portion of the
Project; provided,  however, that, prior to any such sale, lease, or retirement,
the  Company  shall have  provided  to the Issuer  and the  Trustee a  Favorable
Opinion.  The net proceeds from such sale, lease or other  disposition,  if any,
shall belong to, and may be used for any lawful purpose by, the Company.

     Section 3.06.  INSURANCE AND CONDEMNATION  AWARDS.  The net proceeds of any
insurance or  condemnation  award as a result of the destruction or condemnation
of the Project or any portion  thereof  shall belong to, and may be used for any
lawful purpose by, the Company.

     Section 3.07. TAXATION OF PROJECT.  Subject to Section 1.03 hereof,  during
the term of this  Agreement the Company will promptly  remit when due all taxes,
including  specifically all sales taxes and ad valorem taxes,  levied in respect
of the Project or the Installment  Payments payable hereunder to the appropriate
taxing body.  The Company  may, at its own expense and in its own name,  in good
faith contest any such taxes, assessments and other charges and, in the event of
such contest, may permit the taxes, assessments or other charges so contested to
remain  unpaid during the period of such contest and any appeal  therefrom.  All
taxes,  assessments  and other  charges  levied or imposed  with  respect to the
Project  shall be the  obligation  of the Company,  and the Issuer shall have no
obligation or liability in this regard.

     Section  3.08.  ISSUER'S  LIMITED  LIABILITY.  It is  recognized  that  the
Issuer's only source of funds with which to carry out its commitments under this
Agreement  will be from the  proceeds  from  the  sale of the  Bonds or from any
available income or earnings derived  therefrom,  from payment made or caused to
be made by the Company  hereunder,  or from any funds which  otherwise  might be
made available by the Company;  and it is expressly agreed that the Issuer shall
have no financial liability,  obligation, or responsibility with respect to this
Agreement  or the  Project  except to the  extent of funds  available  from such
sources.

     Section 3.09.  GOVERNMENTAL  REGULATION.  The Company recognizes and agrees
that this  Agreement  and the  issuance  of the Bonds  pursuant  hereto will not
diminish or limit the  authority of the United States  Environmental  Protection
Agency,  the Texas Natural Resources  Conservation  Commission,  the Texas Water
Development  Board, or any other State agency or local governments in performing
any of the powers,  functions  and duties vested in such entities by federal and
state laws,  and that all  applicable  laws shall be enforced  without regard to
ownership  of the  Project;  and that the  Company  will not be  relieved of any
responsibility  under  any  applicable  federal  or  state  laws or  regulations
pertaining  to  pollution   control,   either  now,  or  during,  or  after  the
acquisition,  construction and improvement of the Project,  and the Issuer shall
have no responsibility or obligation to take any action to comply with such laws
or regulations with respect to the Project.

                             PAYMENTS; DISBURSEMENTS

     Section  4.01.  ISSUANCE  OF  BONDS.  In order  to  provide  funds  for the
refunding of the Prior Bonds,  the Issuer,  concurrently  with the  execution of
this Agreement,  will sell, issue and deliver to the initial  purchasers thereof
the Bonds, all in accordance with the Indenture.  The Issuer agrees to pay, from
the  proceeds  from the sale and  delivery of the Bonds,  or from any  available
income or earnings derived therefrom, or from any funds which otherwise might be
made  available to the Issuer for such  purpose by the Company,  the cost of the
Refunding of the Prior Bonds,  to the full extent provided in this Agreement and
permitted by the Acts.

     Section  4.02.  BOND  PROCEEDS.  

     (a) The Issuer shall cause to be deposited  into a separate  account within
the bond fund established pursuant to the Prior Indenture proceeds from the sale
of the Bonds equal to  $63,300,000,  and the Company shall cause to be deposited
into such separate account the amount of $4,391,437.50,  which together shall be
sufficient to pay the redemption price of  $67,691,437.50  and redeem all of the
Prior Bonds on September 15, 1996.

     (b) The Company  agrees to pay all fees,  charges and expenses of the Prior
Trustee as required by the Prior Indenture.

     Section 4.03.  SECURITY FOR THE BONDS.  Subject to Section 1.03 hereof, the
obligations of WTU, PSO and CPL under this Agreement, including specifically the
obligation to make  Installment  Payments as provided in Sections 5.01, 5.03 and
5.04 hereof,  shall be direct  several  obligations of each of WTU, PSO and CPL,
respectively.  Prior to or simulta-  neously with the issuance of the Bonds, the
Issuer will assign to the Trustee  under the terms of the  Indenture  all of the
Issuer's  right,  title,  and  interest in and to the  Installment  Payments and
certain other rights under this Agreement as provided in the Indenture.

     Section  4.04.  BOND FUNDS.  The Issuer has  authorized  and  directed  the
Trustee  pursuant to the Indenture to transfer all of the proceeds from the sale
of the Bonds to the Prior  Trustee,  as trustee  and paying  agent for the Prior
Bonds.  The  Company  agrees  (i) to direct  the Prior  Trustee  to invest  such
proceeds, together with amounts provided by the Company pursuant to Section 4.05
hereof,  only in direct  obligations of the United States of America,  including
obligations  the  principal  of  and  interest  on  which  are   unconditionally
guaranteed by the United States of America, which may be in book-entry form, and
which mature on or before the redemption  date for the Prior Bonds and (ii) that
any such funds which cannot be so invested shall remain uninvested.

     Section 4.05.  COMPANY REQUIRED TO PAY IN EVENT MONIES HELD PURSUANT TO THE
PRIOR INDENTURE ARE INSUFFICIENT. The Company shall, on the Issue Date, cause to
be  deposited  in the bond fund for the Prior  Bonds  held by the Prior  Trustee
monies  sufficient,  together with the Bond proceeds so transferred on the Issue
Date, without  investment,  to pay the total redemption price of the Prior Bonds
on their  redemption  date, plus any fees and charges due the Prior Trustee.  In
the event that monies held pursuant to the Prior Indenture are not sufficient to
accomplish the Refunding on the redemption date for the Prior Bonds, the Company
shall at its own  expense  and  without  any right of  reimbursement  in respect
thereof  immediately  pay that portion of such costs as may be in excess of said
monies.

     Section  4.06.  NOTICE TO BOND  INSURER.  The Agent  agrees to give written
notice to Bond Insurer not less than two days prior to any  regularly  scheduled
payment date for principal of or interest on the Bonds if any of WTU, PSO or CPL
do not intend or will be unable to make the corresponding payment to the Trustee
hereunder.

                             THE COMPANY'S PAYMENTS

     Section 5.01.  COMPANY  APPROVAL OF ISSUANCE OF BONDS.  (a)  Simultaneously
with the  authorization  of this  Agreement  by the  Board of  Directors  of the
Issuer,  such Board has adopted the Bond  Resolution.  In  consideration  of the
covenants and agreements set forth in this  Agreement,  and to enable the Issuer
to issue the Bonds to carry out the intents and purposes hereof,  this Agreement
is executed to assure the issuance of such Bonds, and to provide for the due and
punctual  payment by the  Company to the  Issuer,  or to the  Trustee  under the
Indenture,  of amounts  not less than  those  required  to pay,  as and when due
(whether at stated maturity, upon redemption,  acceleration of maturity, tender,
deemed tender, or otherwise),  all of the principal of, redemption  premium,  if
any, and interest on, and Purchase  Price of, the Bonds,  and all other payments
required in connection with such Bonds,  the Agreement,  or the Indenture.  Each
such payment is hereby designated as an "Installment  Payment", and collectively
such  payments  are hereby  designated  as  "Installment  Payments".  Subject to
Section 1.03 hereof,  the Company  hereby  agrees to make,  or cause to be made,
each Installment  Payment, as and when due, for the benefit of the owners of the
Bonds into the Bond Fund, or, in the case of an  Installment  Payment in respect
of  Purchase  Price,  into  the  Bond  Purchase  Fund,  all as  provided  in the
Indenture.

     (b) By  execution  and  delivery  of this  Agreement,  the  Company  hereby
approves the Bond  Resolution  and the  Indenture.  It is hereby agreed that the
foregoing  approval of the Bond  Resolution  and the Indenture  constitutes  the
acknowledgement and agreement of the Company that the Bonds, when issued,  sold,
and  delivered as provided in the Bond  Resolution  and the  Indenture,  will be
issued in accordance with and in compliance with this Agreement, notwithstanding
any other provisions of this Agreement or any other contract or agreement to the
contrary.  Any Bondholder is entitled to rely fully and  unconditionally  on the
foregoing  approval.  Notwithstanding  any  provisions of this  Agreement or any
other contract or agreement to the contrary,  the Company's approval of the Bond
Resolution and the Indenture shall be the Company's agreement that all covenants
and provisions in this Agreement and the Indenture  affecting the Company shall,
upon the delivery of the Bonds and the Indenture,  become unconditional,  valid,
and binding  covenants and  obligations  of the Company so long as the Bonds and
the interest thereon are outstanding and unpaid. Particularly, the obligation of
the Company to make,  promptly when due, all Installment  Payments  specified in
this Agreement and the Indenture shall be absolute and unconditional, subject to
Section 1.03  hereof,  and said  obligation  may be enforced as provided in this
Agreement and the Indenture.

     Section  5.02.  REFUNDING OF BONDS.  After the  issuance of any Bonds,  the
Issuer  shall not  refund  any of the Bonds or change or modify the Bonds in any
way, except as provided for in the Indenture, without the prior written approval
of the Authorized  Agent  Representative;  nor shall the Issuer redeem any Bonds
prior to their  scheduled  maturities  except upon the request of the Authorized
Agent Representative, unless such redemption is required by the Indenture.

     Section  5.03.  PAYMENT  UPON  REDEMPTION  OF BONDS.  The Issuer,  upon the
written  request of the Agent (and provided that the affected  Bonds are subject
to redemption or  prepayment  prior to maturity at the option of the Issuer,  or
the Company, and provided that such request is received in sufficient time prior
to the date upon which such  redemption or  prepayment  is proposed),  forthwith
shall  take or cause to be taken  all  action  that may be  necessary  under the
applicable  redemption  provisions  of the  Indenture to effect such  redemption
prior to maturity,  to the full extent of funds either made  available  for such
purpose by the Company or already on deposit  under the  Indenture and available
for such purpose.  The redemption of any outstanding  Bonds prior to maturity at
any time  shall not  relieve  the  Company  of its  absolute  and  unconditional
obligation  to pay  each  remaining  Installment  Payment  with  respect  to any
Outstanding  Bonds,  as specified in the Indenture.  If a redemption of Bonds is
required  pursuant to the  provisions of the  Indenture,  the Company  agrees as
provided  herein to forthwith make  Installment  Payments  sufficient to pay the
principal of, premium, if any, and interest on the Bonds.

     Section 5.04.  INSTALLMENT  PAYMENTS.  Payment of all Installment  Payments
shall be made and  deposited  so as to fund  payment on the Bonds as required by
the  Indenture,  including all such  payments  which may come due because of the
acceleration  of the maturity or maturities of the Bonds upon default,  call for
redemption,  purchase or deemed purchase, or otherwise,  under the provisions of
the Indenture. If any available funds in excess of current requirements are held
on deposit in the Bond Fund or the Bond  Purchase  Fund,  as the case may be, at
the time payment of any Installment  Payment is due, such payment of Installment
Payment  shall  be  reduced  by the  amount  of the  available  funds so held on
deposit, to the benefit of the Company. The Installment Payments,  together with
available  funds held on deposit in the Bond Fund or the Bond Purchase  Fund, as
the case may be,  except funds held therein for payment of matured  installments
of principal on the Bonds or interest  payable  thereon,  shall be sufficient to
pay when due all principal of, redemption  premium, if any, and interest on, and
Purchase  Price of, the  Bonds.  The  Company  shall have the right to prepay or
cause to be prepaid  all or a portion of each  Installment  Payment at any time,
and shall be  obligated  to do so in a timely  manner if and to the  extent  the
Agent requests redemption or prepayment of the Bonds. Any such prepayment by the
Company shall not relieve it of liability for each remaining Installment Payment
with respect to the  Outstanding  Bonds except as provided in this Agreement and
the Indenture.  In the event the Company should fail to make any of the payments
required in this Section  5.04,  the amount so in default  shall  continue as an
obligation  of the Company  until such  amount in default  shall have been fully
paid.  If the  amount on  deposit in any fund is  insufficient  on any  Interest
Payment Date,  redemption  date or Purchase  Date to make timely  payment due on
such date,  the Company shall deposit  sufficient  moneys in such fund to enable
timely payment to be made on such date, subject to Section 1.03 hereof.

     Section 5.05.  PAYMENTS TO ISSUER.  Out of money from the proceeds from the
sale and delivery of the Bonds or out of funds  provided by the  Company,  there
shall be paid all of the Issuer's reasonable actual  out-of-pocket  expenses and
Costs of Issuance in connection  with the Bonds.  In addition,  the Issuer shall
receive out of  proceeds  of the Bonds or from funds  advanced by the Company an
amount equal to 1/2 of 1% of the aggregate  principal amount of the Bonds to pay
and reimburse the Issuer for its  administrative  and overhead expenses directly
attributable  and  chargeable  to the  issuance  of the Bonds.  Also the Company
agrees to pay  directly  to the  Issuer on July 1 of each year  while any of the
Bonds are outstanding, an amount equal to $3,500 to pay and reimburse the Issuer
for its annual  administrative  and overhead expenses directly  attributable and
chargeable  to the  administration  of the Bonds  during the prior  twelve month
period.

     Section 5.06.  ISSUER'S RIGHTS ASSIGNED TO TRUSTEE.  The Company is advised
and  recognizes  that as security for the payment of the Bonds,  the Issuer will
assign to the Trustee the Issuer's  rights under this  Agreement,  including the
right to receive payments  hereunder (except the right to receive  payments,  if
any, under Section 5.05, 6.03, and 7.03 hereof),  and hereby directs the Company
to make said payments  directly to the Trustee.  The Company herewith assents to
such  assignment  and will make such  payments  directly to the Trustee  without
defense or set-off by reason of any  dispute  between the Company and the Issuer
or the Trustee.  All rights against the Company  arising under this Agreement or
the Bond Resolution or Indenture and assigned to the Trustee under the Indenture
may be  enforced  by the  Trustee,  or the  owners of the  Bonds,  to the extent
provided in the Indenture, and the Trustee, or the owners of the Bonds, shall be
entitled to bring any suit,  action, or proceeding  against the Company,  to the
extent provided in the Bond Resolution or Indenture, for the enforcement of this
Agreement, and it shall not be necessary in any such suit, action, or proceeding
to make the Issuer a party thereto.

     Section  5.07.  PAYMENTS TO TRUSTEE.  Subject to Section 1.03  hereof,  the
Company  agrees  to pay  (1)  the  initial  acceptance  fee of the  Trustee  and
reasonable costs and expenses,  including reasonable attorneys fees, incurred by
the Trustee in entering into and executing the Indenture and the issuance of the
Bonds and (2) until the principal of, premium, if any, and interest on the Bonds
shall have been fully paid or provision for the payment  thereof shall have been
made in accordance  with the  provisions of the  Indenture,  (i) the  reasonable
annual fee of the Trustee for the ordinary services of the Trustee,  as trustee,
rendered and its  reasonable  ordinary  expenses  incurred  under the Indenture,
including  reasonable  attorneys fees, as and when the same become due, (ii) the
reasonable fees,  charges and expenses of the Trustee,  as Bond Registrar and as
Paying Agent,  and any other Bond Registrar or Paying Agent on the Bonds, as and
when the same become due, (iii) the reasonable fees, charges and expenses of the
Trustee  for  the   necessary   extraordinary   services   rendered  by  it  and
extraordinary expenses incurred by it under the Indenture or this Agreement,  as
and when the same become due,  including  reasonable  attorneys fees;  provided,
that the Company  may,  without  creating a default  hereunder,  contest in good
faith  the  necessity  for any such  extraordinary  services  and  extraordinary
expenses and the reasonableness of any such fees, charges, or expenses, and (iv)
the cost of printing any Bonds  required to be  furnished by the Issuer.  In the
event the  Company  should  fail to make any of the  payments  required  in this
Section  5.07,  the item or  installments  so in default  shall  continue  as an
obligation  of the  Company  until the amount in  default  shall have been fully
paid.

     Section 5.08.  PAYMENT TO REMARKETING  AGENT.  The Company agrees to pay to
the Remarketing  Agent the reasonable  fees, costs and expenses set forth in the
Remarketing Agreement.

     Section  5.09.  COMPANY  OPTION TO DESIGNATE  INTEREST  RATE  DETERMINATION
METHODS. The Company is hereby granted the option to designate from time to time
changes in interest rate  determination  methods in the manner and to the extent
set forth in Section 2.02 of the  Indenture.  In the event the Company elects to
exercise  any such  option,  the Agent  agrees  that it shall  cause  notices of
changes in interest rate  determination  methods to be given to the Issuer,  the
Trustee,  the Paying Agent, and the Remarketing Agent in accordance with Section
2.02 of the Indenture.

     Section 5.10.  PURCHASE OF BONDS.  (a) In  consideration of the issuance of
the Bonds by the  Issuer,  but for the  benefit of the owners of the Bonds,  the
Company  has  agreed,   and  does  hereby  covenant,   to  cause  the  necessary
arrangements to be made and to be thereafter  continued whereby owners from time
to time of the Bonds may deliver Bonds for purchase and whereby such Bonds shall
be so purchased.  In furtherance of the foregoing  covenant of the Company,  the
Issuer,  at the  direction of the Company,  has set forth in Section 2.10 of the
Indenture  the terms and  conditions  relating  to the  delivery of Bonds by the
registered  holders  thereof to the  Remarketing  Agent for purchase and has set
forth  in  the   Indenture  or  the   Remarketing   Agreement   the  duties  and
responsibilities  of the  Remarketing  Agent with  respect to the  purchase  and
remarketing of Bonds. The Company hereby  authorizes and directs the Remarketing
Agent to  purchase,  offer,  sell,  and  deliver  Bonds in  accordance  with the
provisions of Section 2.10 of the Indenture.

     Without limiting the generality of the foregoing covenant of the Company or
the other provisions of this Article V, the Company  covenants,  for the benefit
of the owners of the Bonds,  to pay, or cause to be paid,  to the  Trustee  such
amounts as shall be necessary to enable the Trustee to pay the Purchase Price of
the Bonds delivered to it for purchase or deemed delivered for purchase,  all as
more  particularly  described  in the  Indenture;  provided,  however,  that the
obligation  of the  Company  to make,  or cause  to be  made,  any such  payment
hereunder  shall be subject to Section  1.03  hereof and shall be reduced to the
extent  that funds are  received  by the  Trustee  or the Paying  Agent from the
remarketing of the Bonds by the  Remarketing  Agent or, in the event  sufficient
funds are not available from such remarketing, from the Company.

     (b) The Issuer shall have no  obligation  or  responsibility,  financial or
otherwise,  with respect to the purchase of Bonds or the making or  continuation
of arrangements  therefor other than as expressly set forth in subsection (a) of
this Section 5.10,  except that the Issuer shall  generally  cooperate  with the
Company and the Remarketing Agent as contemplated by the Indenture.

     Section 5.11. USURY. Anything herein to the contrary notwithstanding, it is
the  intention  of the parties  hereto to conform  strictly to the usury laws in
force that are applicable to this transaction. Accordingly, all agreements among
the parties  hereto and  beneficiaries  hereof and their assigns or any of them,
whether now  existing or hereafter  arising,  and whether  written or oral,  are
hereby limited so that in no  contingency,  whether by reason of acceleration of
amounts due  hereunder  or any part  thereof or  otherwise,  shall the  interest
(including all sums that are deemed to be interest)  contracted for,  charged or
received  hereunder and/or with respect to the refinancing of the Project exceed
the maximum amount  permissible  under  applicable law. The parties hereto agree
that to the extent  interest  is payable by the  Company  under this  Agreement,
Article 5069-1.04,  Vernon's Texas Civil Statutes, as amended, shall apply, and,
to the extent Article  5069-1.04 is applicable to this Agreement,  the indicated
rate ceiling thereunder shall apply.

                              DEFAULTS AND REMEDIES

     Section 6.01. EVENTS OF DEFAULT. The occurrence and continuation of any one
of the following shall constitute an "Event of Default" under this Agreement (an
"Event of Default"):

     (a) failure by any of WTU, PSO or CPL to pay its  Ownership  Percentage  of
Installment  Payments with respect to principal of or premium on any Bond at the
times specified therein; or

     (b) failure by any of WTU, PSO or CPL to pay its  Ownership  Percentage  of
Installment Payments with respect to interest on any Bond at the times specified
therein  and (i) if such Bond  bears  interest  at a  Flexible,  Daily,  Weekly,
Monthly,  Quarterly or Semiannual  Rate, the  continuation of such failure for a
period of one  Business  Day or more or (ii) if such Bond  bears  interest  at a
Multiannual  or Fixed Rate,  the  continuation  of such  failure for a period of
sixty days or more; or

     (c) failure by any of WTU, PSO or CPL to pay its  Ownership  Percentage  of
Installment Payments with respect to the Purchase Price of any Bond at the times
specified  therein  and the  continuation  of such  failure  for a period of one
Business Day or more; or

     (d) failure by any of WTU, PSO or CPL to observe and perform any  covenant,
condition or agreement on its part  required to be observed or performed in this
Agreement,  other than as referred to in (a), (b) or (c) above,  for a period of
90 days after receipt by the Agent of written notice specifying such failure and
requesting that it be remedied, given to the Agent by the Issuer or the Trustee,
unless the Issuer and the Trustee shall agree in writing to an extension of such
time prior to its expiration; provided, howev- er, that if the failure stated in
the notice  can, in the  reasonable  judgment of the Agent,  be  corrected,  but
cannot be corrected  within the  applicable  period,  the Issuer and the Trustee
will not  unreasonably  withhold  their  consent to an extension of such time if
corrective  action is instituted  within the  applicable  period and  diligently
pursued until the default is corrected; or

          (e) dissolution or liquidation of any of WTU, PSO & CPL. However,  the
     term "dissolution or liquidation of any of WTU, PSO & CPL", as used in this
     paragraph, shall not be construed to include the cessation of the corporate
     existence  of any of WTU,  PSO,  or CPL  resulting  either from a merger or
     consolidation of any of WTU, PSO & CPL into or with another  corporation or
     a dissolution  or liquidation of any of WTU, PSO & CPL following a transfer
     of all  or  substantially  all  of its  assets  as an  entirety  under  the
     conditions permitting such actions contained in Section 7.02; or

          (f) any of WTU,  PSO & CPL shall  commence a  voluntary  case or other
     proceeding  seeking  liquidation,  reorganization,  or  other  relief  with
     respect to itself or its debts under any bankruptcy,  insolvency,  or other
     similar  law now or  hereafter  in effect or seeking the  appointment  of a
     trustee, receiver,  liquidator,  custodian, or other similar official of it
     or any  substantial  part of its  property,  or shall  consent  to any such
     relief or to the  appointment of or taking  possession by any such official
     in an involuntary case or other proceeding  commenced  against it, or shall
     make a general  assignment  for the  benefit  of  creditors,  or shall fail
     generally to pay its debts as they become due, or shall take any  corporate
     action to authorize any of the foregoing; or

               (g) an involuntary  case or other  proceeding  shall be commenced
     against any of WTU, PSO or CPL seeking liquidation, reorganization, or
     other  relief with  respect to it or its debts  under any  bankruptcy,
     insolvency, or other similar law now or hereafter in effect or seeking
     the  appointment of a trustee,  receiver,  liquidator,  custodian,  or
     other similar  official of it or any substantial part of its property,
     and such involuntary case or other proceeding shall remain undismissed
     and unstayed for a period of sixty (60) days; or

               (h) the occurrence of an "Event of Default" under the Indenture.

     The  provisions  of  paragraph  (d) of this Section 6.01 are subject to the
following limitations:  if by reason of acts of God, strikes,  lockouts or other
industrial  disturbances;  acts of public enemies;  orders or regulations of any
kind of the  government of the United States of America or of the State of Texas
or any of their departments,  agencies, political subdivisions, or officials, or
any civil military authority;  insurrections;  riots;  epidemics;  land- slides;
lightning;   earthquakes;  tidal  waves;  fires;  hurricanes;   tornadoes;  blue
northers;  other storms;  floods;  washouts;  droughts;  arrests;  restraints of
government and people; civil disturbances;  explosions;  breakage or accident to
machinery,  transmission pipes,  transmission  facilities or canals;  partial or
entire  failure  of  utilities;   shortages  of  labor,  material,  supplies  or
transportation; or any other cause or event not reasonably within the control of
the Company (collectively,  "events of force majeure"), the Company is unable in
whole  or in part to carry  out the  agreements  on the  Company's  part  herein
contained,  the Company shall not be deemed in default during the continuance of
such inability.  The Company,  however, will use its best efforts to remedy with
all reasonable dispatch the cause or causes preventing the Company from carrying
out such  agreements;  provided,  that the  settlement of strikes,  lockouts and
other  industrial  disturbances  shall be entirely  within the discretion of the
Company,  and the Company  shall not be required to make  settlement of strikes,
lockouts,  and other  industrial  disturbances by acceding to the demands of the
opposing  party or parties  when such  course is, in the  judgment of the Agent,
unfavorable  to the Company.  The occurrence of any event of force majeure shall
not suspend or otherwise  abate, and the Company shall not be relieved from, any
obligation under this Agreement to the extent that the failure of the Company to
observe or perform any such  obligation  would result in the failure to pay when
due the principal of, premium, if any, and interest on the Bonds or would result
in the  interest on any Bonds  becoming  includable  in the gross  income of the
owners thereof for federal income tax purposes.

     The above provisions, however, are subject to the condition that, after any
such  Event  of  Default,  subject  to  and as  provided  in  Article  VI of the
Indenture, the Trustee may waive such Event of Default and rescind and annul any
remedial  step  theretofore  taken by it or by the Issuer  with  respect to such
default and its consequences;  but no such waiver, rescission or annulment shall
extend  to or  affect  any  subsequent  default  or  impair  any right or remedy
consequent thereon.

     Section 6.02. REMEDIES ON DEFAULT. Whenever any Event of Default shall have
occurred and is continuing,  the Issuer, with the consent of the Trustee, or the
Trustee may take any one or more of the following  remedial  steps,  but only if
acceleration of the principal amount of the Bonds has been declared  pursuant to
Section 6.02 of the Indenture:

     (a) By notice in  writing  to the Agent,  declare  the  unpaid  Installment
Payments to be due and payable  immediately,  if  concurrently  with or prior to
such notice the unpaid principal amount of the Bonds has been declared to be due
and  payable  under the  Indenture,  and upon any such  declaration  the amounts
payable  under  Sections  5.01  and  5.04  hereof  shall  become  and  shall  be
immediately  due and  payable in the  amount  set forth in  Section  6.02 of the
Indenture;  provided,  however,  that an Event of Default shall be deemed waived
and a declaration  accelerating  payment of unpaid Installment  Payments payable
under this Agreement  shall be deemed  rescinded  without  further action on the
part of the  Trustee or the Issuer  upon any  rescission  by the  Trustee of the
corresponding declaration of acceleration of the Bonds under Section 6.02 of the
Indenture.

     (b) Whatever  action at law or in equity may appear  necessary or desirable
to collect the payment and other amounts then due or to enforce  performance and
observance  of any  obligation,  agreement or covenant of any of WTU, PSO or CPL
under this Agreement.

     In case the Issuer,  with the consent of the Trustee,  or the Trustee shall
have proceeded to enforce its rights under this  Agreement and such  proceedings
shall  have been  discontinued  or  abandoned  for any reason or shall have been
determined  adversely to the Issuer  and/or the Trustee,  then and in every such
case the  Issuer,  the Agent,  the  Company  and the  Trustee  shall be restored
respectively to their several  positions and rights  hereunder,  and all rights,
remedies and powers of the Issuer, the Company and the Trustee shall continue as
though no such proceeding had been taken.

     Subject to Section  1.03 hereof,  the Company  covenants  that,  in case an
Event of Default  shall  occur with  respect to the  payment of any  Installment
Payment  payable under Sections 5.01 and 5.04 hereof,  then,  upon demand of the
Trustee,  the Company  will pay to the Trustee the whole  amount that then shall
have become due and payable under said Sections 5.01 and 5.04, with interest (to
the extent permitted by law) on such amount at the rate of interest borne by the
Bonds at the time of such failure from the due date thereof until paid.



     Subject to Section 1.03 hereof, in case the Company shall fail forthwith to
pay such amounts upon such demand,  the Trustee  shall be entitled and empowered
to institute any action or proceeding at law or in equity for the  collection of
the sums so due and unpaid,  and may  prosecute any such action or proceeding to
judgment or final  decree,  and may enforce  any such  judgment or final  decree
against  the  Company  and  collect  in the  manner  provided  by law out of the
property of the Company, the moneys adjudged or decreed to be payable.

     The remedies  for any "Event of Default"  under the  Indenture  shall be as
specified  in Article VI of the  Indenture  and are in addition to any  remedies
hereunder.

     In acting or omitting to act pursuant to the provisions of this  Agreement,
the Trustee shall be entitled to all of the rights,  protections  and immunities
accorded  to the Trustee  under the terms of the  Indenture,  including  but not
limited to those set out in Article VII thereof.

     Section 6.03.  AGREEMENT TO PAY ATTORNEYS' FEES AND EXPENSES.  In the event
the Company  defaults  under any of the  provisions  of this  Agreement  and the
Issuer or the  Trustee  employs  attorneys  or  incurs  other  expenses  for the
collection  of the  payments  due under this  Agreement  or the  enforcement  of
performance  or  observance  of any  obligation  or agreement on the part of the
Company herein  contained,  the Company agrees,  subject to Section 1.03 hereof,
that it will on demand therefor,  and upon presentation of an itemized bill, pay
to the Issuer or the  Trustee the  reasonable  fees of such  attorneys  and such
other expenses so incurred by the Issuer or the Trustee; provided,  however, the
Company,  without  creating  a default  hereunder  or under the  Indenture,  may
contest in good faith the necessity for and the  reasonableness of any such fees
and expenses of the Trustee.




                                   ARTICLE VII
 
                                SPECIAL COVENANTS

     Section 7.01. NO DEFENSE OR SET-OFF;  UNCONDITIONAL OBLIGATION.  Subject to
Section  1.03  hereof,  the  obligations  of the  Company  to make the  payments
required by this  Agreement  and to perform and observe the other  agreements on
its part contained herein shall be absolute and  unconditional,  irrespective of
any  defense or any  rights of  set-off,  recoupment  or  counterclaim  it might
otherwise have against the Issuer or any other person, and the Company shall pay
during the term of this  Agreement  the  payments  to be made as  prescribed  in
Sections  5.01,  5.03,  5.04,  5.05 or  5.10  and all  other  payments  required
hereunder free of any deductions and without  abatement,  diminution or set-off;
and until such time as the  principal of,  premium,  if any, and interest on the
Bonds shall have been fully paid,  or provision  for the payment  thereof  shall
have been made in  accordance  with the Inden- ture,  the Company:  (i) will not
suspend or discontinue any payments  provided for in Sections 5.01,  5.03, 5.04,
5.05 or 5.10 hereof;  (ii) will perform and observe all of its other  agreements
contained in this  Agreement;  and (iii) except as  permitted  herein,  will not
terminate  this  Agreement  for  any  cause,  including,  without  limiting  the
generality  of the  foregoing,  failure  of the  Company  to  use  the  Project,
destruction of or damage to the Project,  commercial frustration of purpose, any
change in the tax laws of the  United  States of  America or of the State or any
political  subdivision  of either of these,  or any failure of the Issuer or the
Trustee to perform and observe any agreement, whether express or implied, or any
duty, liability or obligation arising out of or connected with this Agreement or
the  Indenture,  except  to the  extent  permitted  by this  Agreement.  Nothing
contained  in this  Section  shall be  construed  to  relieve  the Issuer or the
Trustee  from  the  performance  of any  agreements  on their  respective  parts
contained  herein and the Company  shall be entitled  to  institute  such action
against  the Issuer or the  Trustee as the  Company  shall deem  appropriate  to
compel performance of any such agreement, duty or obligation; provided, however,
that the Issuer shall not be required to carry out any such  agreement,  duty or
obligation  unless it is reimbursed for its costs and expenses and no agreement,
duty or obligation of the Issuer shall arise out of this Agreement other than as
specifically set forth herein.

     Section 7.02. CORPORATE EXISTENCE.  Each of WTU, PSO and CPL agrees that it
will not  dispose  of all or  substantially  all of its  assets  as an  entirety
(whether by  liquidation,  dissolution,  or otherwise) and will not  consolidate
with or merge into another  corporation,  or permit one or more  corporations to
consolidate  with  or  merge  into  it,  unless  the  resulting,  surviving,  or
transferee  corporation,  as the case may be, if other than WTU,  PSO or CPL, as
the case may be,  irrevocably  and  unconditionally  assumes,  in an  instrument
delivered to the Issuer and to the Trustee,  the due and punctual performance of
the  obligations  of WTU, PSO or CPL, as the case may be, under this  Agreement.
Upon the delivery of such instrument, WTU, PSO or CPL, as the case may be, shall
thereupon  be  relieved  of any  further  obligation  or  liability  under  this
Agreement  or with  respect  to the  Bonds;  and the  resulting,  surviving,  or
transferee corporation,  as the case may be, shall succeed to and be substituted
for WTU,  PSO or CPL,  as the case may be,  under this  Agreement  with the same
effect as if such  resulting or surviving  corporation  or  transferee  had been
named herein as WTU, PSO or CPL, as the case may be. If  consolidation,  merger,
or sale,  or other  transfer  is made as  provided  in this  Section  7.02,  the
provisions  of this Section 7.02 shall  continue in full force and effect and no
further consolidation, merger, or sale or other transfer shall be made except in
compliance with the provisions of this Section 7.02.

     Section 7.03.  INDEMNITIES.  The Company releases the Issuer, its officers,
directors,  employees,  agents,  and attorneys  (collectively,  the "Indemnified
Parties")  from,  and the  Indemnified  Parties shall not be liable for, and the
Company agrees, and shall be liable to protect, indemnify,  defend, and hold the
Indemnified Parties harmless from any and all liability,  cost, expense, damage,
or loss of whatever  nature  (including,  but not limited to,  attorneys'  fees,
litigation  and court  costs,  amounts paid in  settlement,  and amounts paid to
discharge  judgments) directly or indirectly  resulting from, arising out of, in
connection with, or related to (i) the issuance,  offering,  sale or delivery of
the Bonds, the Indenture,  this Agreement, and the obligations imposed on Issuer
hereby and thereby; or the design, construction,  installation,  operation, use,
occupancy, maintenance, or ownership of the Project; (ii) any written statements
or  representations  made or given by the  Company,  or any of its  officers  or
employees,  to the  Indemnified  Parties,  the Trustee,  or any  underwriters or
purchasers  of any of the Bonds,  with respect to the Issuer,  the Company,  the
Project,   or  the  Bonds,   including,   but  not  limited  to,  statements  or
representations of facts,  financial  information,  or corporate affairs;  (iii)
damage  to  property  or any  injury  to or  death  of any  person  that  may be
occasioned by any cause whatsoever  pertaining to the Project; and (iv) any loss
or damage  incurred by the Issuer as a result of violation by the Company of the
provisions of the Prior Agreement or Section 7.04 or 7.05 hereof. The provisions
of the preceding  sentence  shall remain and be in full force and effect even if
any such  liability,  cost,  expense,  damage,  or loss or claim therefor by any
person,  directly or indirectly results from, arises out of, or relates to or is
asserted  to have  resulted  from,  arisen out of, or related to, in whole or in
part,  one or more  negligent  acts or omissions of the Issuer or its  officers,
directors,  employees,  agents,  servants,  or any other party  acting for or on
behalf of the Issuer in  connection  with the  matters  set forth in clauses (i)
through (iv) of said sentence.

     Section 7.04.  TAX-EXEMPT  STATUS OF THE BONDS.  It is the intention of the
Company and the Issuer that the  interest  on the Bonds be  excludable  from the
gross income of the holders thereof for federal income tax purposes,  except for
any  Bond  for  any  period  that  such  Bond  is  owned  by a  person  who is a
"substantial  user" of the Project or a "related  person"  within the meaning of
Section  103(b)(13) of the Internal  Revenue Code of 1954 (the "1954 Code").  To
that end,  the  Company  and the  Issuer (to the  extent  reasonably  within the
control of the Issuer)  covenant  with each other,  and with the Trustee for the
benefit of the  Bondholders,  to refrain from any action  which would  adversely
affect,  and to take  such  action  to  assure,  the  treatment  of the Bonds as
obligations  described in Section 103 (a) of the Code,  the interest on which is
not  includable in the "gross  income" of the holder (other than the income of a
"substantial  user" of the Project or a "related  person"  within the meaning of
Section  103(b)(13) of the 1954 Code) for purposes of federal  income  taxation.
Furthermore, the Company hereby covenants as follows:

     (a) to use all of the proceeds of the Bonds for the payment of principal on
the Prior Bonds;

     (b) to refrain  from using the  facilities  constituting  the  Project in a
manner that would result in the Bonds not being "exempt  facility  bonds" within
the meaning of Section 103(b)(4) of the 1954 Code.

     (c) to refrain  from taking any action that would result in the Bonds being
"federally guaranteed" within the meaning of Section 149(b) of the Code;



     (d) to  refrain  from  using any  portion  of the  proceeds  of the  Bonds,
directly or indirectly, to acquire or to replace funds which were used, directly
or indirectly,  to acquire investment  property (as defined in Section 148(b)(2)
of the Code) which produces a materially higher Yield over the term of the Bonds
than the Yield on the Bonds, other than investment property acquired with --

                    (1)  proceeds of the Bonds  invested for a period of 90 days
               or less until such  proceeds are needed for the purpose for which
               the Bonds are issued,

                    (2)  amounts  invested  in a bona  fide debt  service  fund,
               within the meaning of Section 1.148-1 of the Regulations, and

                    (3) amounts deposited in any reasonably  required reserve or
               replacement  fund to the  extent  such  amounts  do not exceed 10
               percent of the proceeds of the Bonds and to the extent that at no
               time during any bond year will the  aggregate  amount so invested
               exceed 150 percent of debt service on the Bonds for such year;



     (e) to  otherwise  restrict  the use or  investment  of the proceeds of the
Bonds or amounts  treated as  proceeds  of the Bonds,  as may be  necessary,  to
satisfy the requirements of Section 148 of the Code (relating to arbitrage);

     (f) to provide to the Trustee, at such time as required by the Trustee, all
information  required by the Trustee with respect to Nonpurpose  Investments not
held in any fund under the Indenture; and

     (g) to use no more than 2 percent  of the gross  proceeds  of the Bonds for
the payment of costs of issuance.

     The terms Nonpurpose Investments, Excess Earnings, and Yield shall have the
meanings  given to such  terms in  section  148 of the Code and the  Regulations
promulgated pursuant to such section.

     It is the  understanding  of the Issuer and the Company that the  covenants
contained  herein  are  intended  to  assure  compliance  with  the Code and any
regulations  or rulings  promulgated  by the  United  States  Department  of the
Treasury  pursuant  thereto.  In the  event  that  regulations  or  rulings  are
hereafter  promulgated  which  modify  or  expand  provisions  of the  Code,  as
applicable  to the Bonds,  the Issuer and the  Company  will not be  required to
comply with any  covenant  contained  herein to the extent that such  failure to
comply, in the opinion of Bond Counsel delivered to the Issuer, the Company, and
the Trustee,  will not  adversely  affect the exclusion of interest on the Bonds
from the gross income of the owners of the Bonds for federal income tax purposes
under  Section  103 of the Code.  In the event that  regulations  or rulings are
hereafter promulgated which impose additional  requirements which are applicable
to the Bonds,  the  Company and the Issuer  agree to comply with the  additional
requirements to the extent  necessary,  in the opinion of Bond Counsel delivered
to the Issuer,  the  Company,  and the  Trustee,  to preserve  the  exclusion of
interest  on the  Bonds  from the gross  income  of the  owners of the Bonds for
federal  income tax purposes  under Section 103 of the Code. In  furtherance  of
such  intention,  the Issuer hereby  authorizes  and directs its Executive  Vice
President and General Manager to execute any documents,  certificates or reports
required by the Code and to make such elections,  on behalf of the Issuer, which
may be permitted by the Code as are consistent with the purpose for the issuance
of the Bonds.

     Section 7.05. ARBITRAGE COVENANTS.  The Issuer and the Company covenant and
agree,  for the benefit of the  Trustee  and the owners of the Bonds,  that they
will not  knowingly  take any action or omit from taking any action within their
respective  control,  which would result in a loss of the exemption from federal
income taxation of interest on the Bonds by virtue of the Bonds being considered
"arbitrage bonds" within the meaning of Section 148 of the Code.



     Section  7.06.  PAYMENT TO REBATE FUND.  The Company  hereby  covenants and
agrees to make the  determinations and to pay any deficiency in the Rebate Fund,
at the times and as described in Section 4.10 of the Indenture. In any event, if
the amount of cash held in the Rebate Fund shall be  insufficient  to permit the
Trustee  to  make  payment  to  the  United  States  of  any  amount  due  under
Section 148(f)(2)  of the Code,  the Company  forthwith  shall pay the amount of
such  insufficiency on such date to the Trustee in immediately  available funds.
The obligations of the Company under this Section 7.06 are direct obligations of
the Company, acting under the authorization of, and on behalf of, the Issuer and
the Issuer shall have no further  obligation  or duty with respect to the Rebate
Fund.

     Section 7.07. QUALIFICATION IN TEXAS. Each of WTU, PSO and CPL agrees that,
so long as it owns and operates the Project,  it will be incorporated  under the
laws of the State or will be qualified to do business in the State.

     Section 7.08. RECORDATION.  The Company agrees that it will record and file
any of the financing  statements  and all  supplements  thereto,  and such other
instruments  as may be required  from time to time to be  recorded or filed,  in
such  manner and in such  places as from time to time may be  required by law in
order fully to preserve  and protect the  securities  of the Owners of the Bonds
and the rights of the Trustee hereunder and under the Indenture.

     Section 7.09. NO PERSONAL LIABILITY. No officer, employee,  representative,
or  agent of the  Issuer  or the  Company  shall be  personally  liable  on this
Agreement.

     Section 7.10. COMPLIANCE WITH RULE 15C2-12. Each of WTU, PSO and CPL hereby
agrees that it will comply  with and perform its duties  under the Rule  15c2-12
Undertakings  dated as of the date of delivery of the Bonds and attached to this
Agreement  as Exhibit A and that the  Issuer  shall  have no  responsibility  or
obligation with respect to compliance with Rule 15c2-12.




                                  ARTICLE VIII

                               GENERAL PROVISIONS

     Section 8.01.  GENERAL  PROVISIONS.  

     (a) The terms of this  Agreement may be enforced as to one or more breaches
either separately or cumulatively.

     (b) No remedy  conferred upon or reserved to the Issuer,  the Company,  the
Trustee,  the Agent or the owners of the Bonds in this  Agreement is intended to
be exclusive of any other available remedy or remedies,  but each and every such
remedy shall be cumulative and shall be in addition to every other remedy now or
hereafter  existing at law or in equity or by  statute.  No delay or omission to
exercise any right or power accruing upon any default,  omission,  or failure of
performance hereunder shall impair any such right or power or shall be construed
to be a waiver thereof,  but any such right and power may be exercised from time
to time and as often as may be deemed  expedient.  In the  event  any  provision
contained in this Agreement  should be breached by the Issuer or the Company and
thereafter duly waived, such waiver shall be limited to the particular breach so
waived and shall not be deemed to waive any other breach of this  Agreement.  No
waiver by either party of any breach by the other party of any of the provisions
of this  Agreement  shall be  construed  as a waiver of any  subsequent  breach,
whether of the same or of a different provision of this Agreement.

     (c)  Headings of the  Sections of this  Agreement  have been  inserted  for
convenience of reference only and in no way shall they affect the interpretation
of any of the provisions of this Agreement.

     (d) This  Agreement is made for the  exclusive  benefit of the Issuer,  the
Bond Insurer,  the Trustee,  the owners of the Bonds, the Agent and the Company,
and their respective  successors and assigns herein  permitted,  and not for any
third party or parties; and nothing in this Agreement,  expressed or implied, is
intended  to confer upon any party or parties  other than the  Issuer,  the Bond
Insurer,  the Trustee,  the owners of the Bonds, the Agent and the Company,  and
their respective successors and assigns herein permitted, any rights or remedies
under  or by  reason  of  this  Agreement.  In  particular,  but  not  by way of
limitation,  the Trustee  shall be a  third-party  beneficiary  for  purposes of
enforcing its rights and the Company's  obligations under Sections 5.07 and 7.03
of this  Agreement  as fully as if the  Trustee  had been a party in  privity of
contract with the Company hereunder.

     Section 8.02. INTENTIONALLY OMITTED.

     Section 8.03. AMENDMENT OF AGREEMENT. No amendment, change, addition to, or
waiver of any of the  provisions  of this  Agreement  shall be binding  upon the
parties hereto unless in writing signed by an authorized officer of each of WTU,
PSO and CPL, the  Authorized  Agent  Representative  and the  Authorized  Issuer
Representative and in compliance with Sections 9.05 and 9.06 of the Indenture. A
copy of any such amendment,  change, addition to, or waiver shall be provided to
the Trustee.  Notwithstanding  any of the foregoing or anything in the Indenture
to the  contrary,  but subject to Section  1.04  hereof,  it is  covenanted  and
agreed,  for the benefit of the holders of the Bonds and the  Trustee,  that the
provisions of this Agreement shall not be amended,  changed, added to, or waived
in any way which  would  relieve,  reduce or  abrogate  the  obligations  of the
Company  to make or pay,  or  cause to be made or paid,  when  due,  any and all
Installment  Payments with respect to any then Outstanding  Bonds, in the manner
and under the terms and conditions provided herein and in the Bond Resolution or
Indenture,  or which would change or affect  Article II,  Sections  5.01,  5.03,
5.04, 5.05, 5.06, 5.10, 6.01, 7.01, 7.02, 8.03, or 8.04 hereof or the provisions
of this  sentence  unless,  in the  judgment  of the  Trustee,  such  change  or
amendment   would  not  materially   adversely   affect  the  interests  of  the
Bondholders.

     Section 8.04. ASSIGNMENT.  Each of WTU, PSO and CPL may assign its interest
in this Agreement in whole or in part,  provided,  however,  no such  assignment
shall  relieve WTU, PSO or CPL, as the case may be, from primary  liability  for
any of its  obligations  hereunder,  and without  limiting the generality of the
foregoing, in the event of any such assignment, WTU, PSO or CPL, as the case may
be, shall continue to remain primarily liable for its payments  specified herein
and for  performance and observance of the other covenants and agreements on its
part herein provided. In addition,  each of WTU, PSO and CPL may also assign its
interest in this  Agreement in connection  with a  consolidation  with or merger
into  another  domestic  corporation,   or  the  sale  or  transfer  of  all  or
substantially all of its assets as an entirety to another domestic  corporation,
if such  transaction  complies  with the  requirements  of Section  7.02 hereof.
Anything in this Agreement notwithstanding, no assignment of the interest of any
of WTU, PSO and CPL in this Agreement shall be effective unless WTU, PSO or CPL,
as the  case  may be,  shall,  on or  prior  to the  effective  date of any such
assignment,  furnish or cause to be  furnished  to the  Issuer  and the  Trustee
notice of such assignment, together with a Favorable Opinion.

     Section 8.05.  TERM OF AGREEMENT.  The term of this Agreement shall be from
the date hereof until all payments  and  indemnities  required to be made by the
Company pursuant hereto shall have been made.

Rate, in which case, the Bonds shall  initially bear interest from July 1, 1996.
Thereafter,  the Bonds shall bear  interest  from the  Interest  Payment Date to
which  interest  has been paid or duly  provided  for, or unless no interest has
been paid or duly  provided for on the Bonds,  in which case from the Issue Date
until  paid,  in each case at the rates set forth in Section  2.02 hereof and as
provided in the Bonds.  If, as shown by the records of the Trustee,  interest on
the Bonds is in default,  Bonds  issued in exchange  for Bonds  surrendered  for
registration  of  transfer or  exchange  shall note such  default and shall bear
interest from the date to which interest has been paid in full on the Bonds, or,
if no interest has been paid on the Bonds,  from the Issue Date. Each Bond shall
bear  interest  on overdue  principal  and, to the extent  permitted  by law, on
overdue  interest  at the  applicable  rate in  effect  on the date  which  such
principal and interest became due and payable.

     With respect to Bonds in the Daily, Flexible, Weekly, Monthly, Quarterly or
Semiannual  Mode, on the Business Day before each Interest  Payment Date and for
Bonds in the  Multiannual  and Fixed  Rate  Mode,  on the  fifteenth  day of the
calendar month prior to each Interest  Payment Date, the Trustee shall calculate
the amount of interest to be paid on the next succeeding  Interest  Payment Date
and  shall,  not later  than 11:00  a.m.,  New York City time,  on such date the
calculation  is made,  notify the Company and the Paying  Agent of the amount of
interest to be paid. Any contest by the Company of the amount  calculated by the
Trustee to be due on an Interest  Payment  Date shall not relieve the Company of
its  obligation  to pay such  amount to enable the  Trustee to pay the  interest
payable on the Bonds on such Interest Payment Date.

     Section 2.02. Interest.  The interest rate on the Bonds, as provided in the
Bonds, will be the lesser of (i) the Maximum Rate or (ii) the rate determined as
provided in this Section  2.02.  In no event shall the Interest  Rate exceed the
Maximum Rate. Initially,  the Bonds shall bear interest at the interest rate set
forth in the Approval  Certificate  determined by the  Underwriter in accordance
with the Mode set forth in the Approval Certificate.  Interest on the Bonds in a
Flexible Mode,  Daily Mode,  Weekly Mode or Monthly Mode shall be payable on the
applicable Interest Payment Date as herein described, computed on the basis of a
365 or 366-day year, as applicable for the number of days actually elapsed based
on the calendar  year in which such Rate Period  commences.  The interest on the
Bonds in a Fixed Rate Mode,  Multiannual Mode, Semiannual Mode or Quarterly Mode
shall be payable on the applicable  Interest  Payment Date as herein  described,
computed on the basis of a 360-day  year of twelve  30-day  months.  While there
exists an Event of Default under this Indenture,  the interest rate on the Bonds
will be the rate on the Bonds on the day before the Event of Default occurred.

                  (A)      Flexible Mode.

                    (1)  Determination  of Flexible Rates. The Flexible Rate for
               Bonds  in the  Flexible  Mode  shall  be  the  rate  of  interest
               determined  by the  Remarketing  Agent,  for each  Interest  Rate
               Period, to be the lowest rate which in its judgment, on the basis
               of prevailing financial market conditions, is necessary on and as
               of the Effective Date, to remarket each Bond having such Interest
               Rate  Period  (as  determined  by  the  Remarketing  Agent)  in a
               secondary  market  transaction  at a price equal to the principal
               amount  thereof,  but not in  excess  of the  Maximum  Rate.  The
               Remarketing  Agent shall  determine the initial  Flexible Rate or
               Rates and  Interest  Rate Period or Periods on or before the date
               of conversion to the Flexible Mode.  Thereafter,  the Remarketing
               Agent shall  redetermine the Flexible Rate for each Interest Rate
               Period and shall redetermine each Interest Rate Period. While any
               Bonds are in the Flexible  Mode,  such Bonds may have  successive
               Interest  Rate  Periods and any Bond may bear  interest at a rate
               and for a period different from any other Bond. The interest rate
               and the  Interest  Rate  Period for each  particular  Bond in the
               Flexible  Mode will be determined  by the  Remarketing  Agent and
               will remain in effect from and including  the  Effective  Date of
               the  Interest   Rate  Period   selected  for  that  Bond  by  the
               Remarketing Agent through the last date thereof.  The Remarketing
               Agent  shall  notify the Paying  Agent of the  Flexible  Rate and
               Interest  Rate  Period by  Electronic  Notice not later than 1:00
               p.m., New York City time, on the Effective Date. The Paying Agent
               shall give written  notice of the Flexible Rate and Interest Rate
               Period to the  Trustee  and the  Agent.  Each  determination  and
               redetermination  of the  Flexible  Rate shall be  conclusive  and
               binding on the Issuer,  the Trustee,  the Paying Agent,  the Bond
               Registrar,  the  Company,  the Agent and the  Bondowners.  If the
               Remarketing  Agent fails for any reason to determine the Flexible
               Rate or Interest  Rate Period for any Bond while in the  Flexible
               Mode, or if for any reason such manner of determination  shall be
               determined  to be  invalid  or  unenforceable,  the Bond shall be
               deemed  to be in an  Interest  Rate  Period  ending  on the  next
               succeeding  day which is  immediately  followed by a Business Day
               and the Flexible  Rate shall be equal to 100% of the rate for the
               Public Securities  Association  Municipal Swap Index as published
               by  Municipal  Market  Data  for 7  day  high-  grade  tax-exempt
               variable rate demand obligations on the day on which such rate is
               determined  or, if such rate is not  published  on that day,  the
               most recent publication of such rate.

                    In determining  the Flexible Rate and  remarketing  Bonds in
               the  Flexible  Mode,  the  Remarketing  Agent shall (i) not offer
               Interest  Rate  Periods  greater  than 270  days,  (ii) not offer
               Interest  Rate  Periods  applicable  to  Bonds  to  be  converted
               extending  beyond the day preceding  any scheduled  conversion of
               the Bonds to another Mode or the final maturity of the Bonds, and
               (iii) follow any written directions of the Agent not inconsistent
               with the  preceding  clauses (i) and (ii) as to the Interest Rate
               Periods to be made available.  The Agent, the Trustee, the Paying
               Agent  and  the  Remarketing  Agent  shall  cooperate  to  ensure
               compliance with this requirement.

                    (2)  Conversions  from  the  Flexible  Mode.  Bonds  in  the
               Flexible  Mode or any portion of such Bonds may be  converted  at
               the  election of the Agent from the  Flexible  Mode to the Daily,
               Weekly, Monthly, Quarterly, Semiannual, Multiannual or Fixed Rate
               Mode as  provided  in the  form of  Bond,  so long as no Event of
               Default  hereunder  exists as  certified  to the  Trustee  by the
               Agent.  Written notice of a conversion of Bonds from the Flexible
               Mode shall be given by the Agent to the Issuer, the Trustee,  the
               Paying Agent,  the Remarketing  Agent and the Rating Agencies not
               fewer than 30 days before the  proposed  Conversion  Date,  which
               date shall be specified by the Agent in such notice and shall not
               be earlier than the day following the  expiration of the Interest
               Rate Period with the  longest  remaining  term then in effect for
               the Bonds to be converted. Prior to the proposed Conversion Date,
               the  Remarketing  Agent shall not offer Interest Rate Periods for
               the  Bonds  to  be  converted   extending   beyond  the  proposed
               Conversion Date. Conversions to the Fixed Rate Mode shall also be
               governed by Section 2.02(H) hereof.
                                                   
                    Notwithstanding  the  foregoing,  if  the  preconditions  to
               conversion to a new Mode  established by the preceding  paragraph
               and  Section  2.02(K)  are not met by 10:30  a.m.,  New York City
               time,  on the  Conversion  Date,  the Paying Agent shall deem the
               proposed  conversion to have failed and shall immediately  notify
               the Trustee,  the Agent and the  Remarketing  Agent and the Bonds
               subject to such failed  conversion  shall  remain in the Flexible
               Mode with an Interest Rate Period  ending on the next  succeeding
               day which is  immediately  followed  by a Business  Day.  In such
               event,  such  Bonds  shall  remain  subject to  mandatory  tender
               pursuant to Section 2.11 hereof. In no event shall the failure of
               Bonds to be converted to another Mode for any reason be deemed to
               be, in and of itself,  an Event of Default under this  Indenture,
               so  long  as the  Purchase  Price  of all  Bonds  required  to be
               purchased is made available as provided above.

                    (3)  Mandatory  Tender for  Purchase.  Bonds in the Flexible
               Mode are subject to mandatory  tender for purchase as provided in
               the form of Bond and in Section 2.11 hereof.

                    (B) Daily Mode.

                    (1)  Determination  of Daily Rates.  The Daily Rate shall be
               the rate of interest determined by the Remarketing Agent for each
               Interest  Rate  Period,  to be  the  lowest  rate  which  in  its
               judgment, on the basis of prevailing financial market conditions,
               would  permit the sale of the Bonds in the Daily Mode at par plus
               accrued  interest  on and as of the  Effective  Date,  but not in
               excess of the Maximum Rate. The Remarketing Agent shall determine
               the initial Daily Rate on or before the date of conversion to the
               Daily Mode.  Thereafter,  the Remarketing Agent shall redetermine
               the Daily Rate for each  subsequent  Interest  Rate Period.  When
               such Bond is in the Daily Mode, the Daily Rate in effect for each
               Interest Rate Period (the "Effective Rate" for such Period) shall
               be  determined  not later  than the  Effective  Date and shall be
               effective  from the  Effective  Date  until  the next  succeeding
               Business Day. The Remarketing Agent shall notify the Paying Agent
               of the Daily Rate by Electronic Notice not later than 10:30 a.m.,
               New York City time,  on such Business Day. The Paying Agent shall
               give  written  notice of the Daily  Rate to the  Trustee  and the
               Agent. Each  determination and  redetermination of the Daily Rate
               shall be conclusive and binding on the Issuer,  the Trustee,  the
               Paying Agent, the Company,  the Agent and the Bondowners.  If for
               any reason the  Remarketing  Agent fails to  determine  the Daily
               Rate  (including,  but not limited to, a failure to determine the
               Daily  Rate for a day that is not a  Business  Day) or if for any
               reason such manner of  determination  shall be  determined  to be
               invalid or  unenforceable,  the Daily Rate to take effect on such
               date will be the Daily  Rate in effect on the day next  preceding
               such date.

                    (2) Conversions  from the Daily Mode. The Bonds in the Daily
               Mode  or any  portion  of  such  Bonds  may be  converted  on any
               Interest Payment Date at the election of the Agent from the Daily
               Mode to the Flexible,  Weekly,  Monthly,  Quarterly,  Semiannual,
               Multiannual  or Fixed Rate Mode as  provided in the form of Bond,
               so long as no Event of Default  hereunder  exists as certified to
               the Trustee by the Agent. Written notice of a conversion from the
               Daily  Mode  shall  be  given by the  Agent  to the  Issuer,  the
               Trustee,  the Paying Agent, the Remarketing  Agent and the Rating
               Agencies not fewer than 30 days prior to the proposed  Conversion
               Date,  which date shall be specified by the Agent in such notice.
               Notice  of a  conversion  of Bonds  from the  Daily  Mode and the
               mandatory  tender of Bonds for purchase on such  Conversion  Date
               shall be given to the owners of such Bonds as provided in Section
               2.02(B)(4) hereof and the form of Bond.  Conversions to the Fixed
               Rate Mode shall also be governed by Section 2.02(H) hereof.

                    Notwithstanding  the  foregoing,  if  the  preconditions  to
               conversion to another Mode established by the preceding paragraph
               and  Section  2.02(K)  are not met by 10:30  a.m.,  New York City
               time,  on the  Conversion  Date,  the Paying Agent shall deem the
               proposed  conversion to have failed and shall immediately  notify
               the Trustee,  the Agent and the Remarketing  Agent, and the Bonds
               shall be  subject  to  mandatory  tender as  provided  in Section
               2.02(B)(4) hereof. In addition, the failed conversion shall cause
               the interest rate on the Bonds subject to such failed  conversion
               to immediately convert to the Flexible Mode with an Interest Rate
               Period  ending on the next  succeeding  day which is  immediately
               followed  by a Business  Day.  In such  event,  such Bonds  shall
               remain  subject to  mandatory  tender  pursuant  to Section  2.11
               hereof. In no event shall the failure of Bonds to be converted to
               another Mode for any reason be deemed to be, in and of itself, an
               Event of Default  under this  Indenture,  so long as the Purchase
               Price of all Bonds  required to be purchased is made available as
               provided herein.

                    (3) Bondowners'  Option to Tender Bonds in Daily Mode. Bonds
               in the Daily Mode are subject to tender,  at the  election of the
               owner  thereof,  in the  manner and  subject  to the  limitations
               described in the form of Bond. The owners of Tendered Bonds shall
               receive on the Delivery Date 100% of the principal  amount of the
               Tendered  Bonds  plus  accrued  interest  to the  Purchase  Date,
               provided that if the Purchase  Date is an Interest  Payment Date,
               accrued interest shall be paid separately, and not as part of the
               Purchase Price on such date. The purchase of Tendered Bonds shall
               not  extinguish  the debt  represented  by such Bonds which shall
               remain Outstanding and unpaid under this Indenture.

                    The Paying Agent shall accept all  Tendered  Bonds  properly
               tendered  to it for  purchase as provided in the form of Bond and
               in this subsection (3); provided,  however, that the Paying Agent
               shall  not  accept  any  Tendered  Bonds and the  Purchase  Price
               therefor  shall not be paid if on the Purchase Date the principal
               of the Bonds shall have been accelerated pursuant to Section 6.02
               hereof and such acceleration shall not have been annulled.

                    Notice of the  Bondholder's  option  to tender  Bonds in the
               Daily Mode shall be given to the Paying  Agent at the time and as
               provided in the form of Bond.  The  Bondowners'  Election  Notice
               delivered  to the Paying Agent at the time and as provided in the
               form of Bond shall be in  substantially  the form provided in the
               form of Bond.

                    As soon as practicable after receiving notice of a tender of
               Bonds  under this  Section,  the Paying  Agent  shall  notify the
               Remarketing  Agent,  the  Agent  and  the  Trustee  by  telephone
               promptly confirmed in writing of the amount of Tendered Bonds and
               the specified Purchase Date.

                    During  the time  Bonds are  issued  in the  book-entry-only
               system,  all Bondowners'  Election  Notices shall be given by the
               Beneficial  Owner in accordance with the procedures of DTC or its
               successor.  The  Remarketing  Agent and the Paying Agent shall be
               entitled  to rely on the  accuracy  of any  Bondowners'  Election
               Notice delivered to the Paying Agent.

                    (4) Mandatory  Tender of Bonds.  Bonds in the Daily Mode are
               subject to mandatory  tender for purchase as provided in the form
               of Bond and in Section 2.11 hereof

                    (C) Weekly Mode.

                    (1)  Determination of Weekly Rates. The Weekly Rate shall be
               the rate of interest determined by the Remarketing Agent for each
               Interest  Rate  Period,  to be  the  lowest  rate  which  in  its
               judgment, on the basis of prevailing financial market conditions,
               would permit the sale of the Bonds in the Weekly Mode at par plus
               accrued  interest  on and as of the  Effective  Date,  but not in
               excess of the Maximum Rate. The Remarketing Agent shall determine
               the  initial  Weekly  Rate on or  before  the date of issue in or
               conversion to the Weekly Mode. Thereafter,  the Remarketing Agent
               shall  redetermine the Weekly Rate for each  subsequent  Interest
               Rate  Period.  The Weekly Rate in effect for each  Interest  Rate
               Period  shall be  determined  not later than the  Effective  Date
               which shall be a Wednesday  unless the  Effective  Date is also a
               Conversion  Date, in which case the  Conversion  Date will be the
               Effective  Date.  The  Remarketing  Agent shall notify the Paying
               Agent of the  Weekly  Rate by  Electronic  Notice  not later than
               10:00 a.m.,  New York City time, on the Effective Date (or if the
               Effective  Date is not a  Business  Day,  on the  next  preceding
               Business  Day). The Paying Agent shall give written notice of the
               Weekly Rate to the Trustee and the Agent. Each  determination and
               redetermination  of the  Weekly  Rate  shall  be  conclusive  and
               binding  on the  Issuer,  the  Trustee,  the  Paying  Agent,  the
               Company,  the Agent and the  Bondowners.  If for any  reason  the
               Remarketing Agent fails to determine the Weekly Rate for any Bond
               or if for any  reason  such  manner  of  determination  shall  be
               determined  to be  invalid  or  unenforceable,  the Bond shall be
               deemed to be in a  Flexible  Mode with an  Interest  Rate  Period
               ending on the next  succeeding day which is immediately  followed
               by a Business Day.

                    (2)  Conversions  from the  Weekly  Mode.  The  Bonds in the
               Weekly Mode or any portion of such Bonds may be  converted on any
               Interest  Payment  Date at the  election  of the  Agent  from the
               Weekly  Mode  to  the  Daily,  Monthly,  Quarterly,   Semiannual,
               Multiannual,  Flexible or Fixed Rate Mode as provided in the form
               of Bond,  so long as no  Event of  Default  hereunder  exists  as
               certified  to the  Trustee  by the  Agent.  Written  notice  of a
               conversion  from the  Weekly  Mode shall be given by the Agent to
               the Issuer, the Trustee,  the Paying Agent, the Remarketing Agent
               and the  Rating  Agencies  not  fewer  than 30 days  prior to the
               proposed  Conversion  Date,  which date shall be specified by the
               Agent in such notice.  Notice of a  conversion  of Bonds from the
               Weekly  Mode and the  mandatory  tender of Bonds for  purchase on
               such  Conversion  Date shall be given to the owners of such Bonds
               as  provided in Section  2.02(C)(4)  hereof and the form of Bond.
               Conversions  to the Fixed  Rate Mode shall  also be  governed  by
               Section 2.02(H) hereof.

                    Notwithstanding  the  foregoing,  if  the  preconditions  to
               conversion to another Mode established by the preceding paragraph
               and  Section  2.02(K)  are not met by 10:30  a.m.,  New York City
               time,  on the  Conversion  Date,  the Paying Agent shall deem the
               proposed  conversion to have failed and shall immediately  notify
               the Trustee,  the Agent and the Remarketing  Agent, and the Bonds
               shall be  subject  to  mandatory  tender as  provided  in Section
               2.02(C)(4) hereof. In addition, the failed conversion shall cause
               the interest rate on the Bonds subject to such failed  conversion
               to immediately convert to the Flexible Mode with an Interest Rate
               Period  ending on the next  succeeding  day which is  immediately
               followed  by a Business  Day.  In such  event,  such Bonds  shall
               remain  subject to  mandatory  tender  pursuant  to Section  2.11
               hereof. In no event shall the failure of Bonds to be converted to
               another Mode for any reason be deemed to be, in and of itself, an
               Event of Default  under this  Indenture,  so long as the Purchase
               Price of all Bonds  required to be purchased is made available as
               provided above.

                    (3) Bondowners' Option to Tender Bonds in Weekly Mode. Bonds
               in the Weekly Mode are subject to tender,  at the election of the
               owner  thereof,  in the  manner and  subject  to the  limitations
               described in the form of Bond. The owners of Tendered Bonds shall
               receive on the Delivery Date 100% of the principal  amount of the
               Tendered  Bonds  plus  accrued  interest  to the  Purchase  Date,
               provided that if the Purchase  Date is an Interest  Payment Date,
               accrued interest shall be paid separately, and not as part of the
               Purchase Price on such date. The purchase of Tendered Bonds shall
               not  extinguish  the debt  represented  by such Bonds which shall
               remain Outstanding and unpaid under this Indenture.

                    The Paying Agent shall accept all  Tendered  Bonds  properly
               tendered  to it for  purchase as provided in the form of Bond and
               in this subsection (3); provided,  however, that the Paying Agent
               shall  not  accept  any  Tendered  Bonds and the  Purchase  Price
               therefor  shall not be paid if on the Purchase Date the principal
               of the Bonds shall have been accelerated pursuant to Section 6.02
               hereof and such acceleration shall not have been annulled.

                    Notice of the  Bondholders'  option  to tender  Bonds in the
               Weekly Mode shall be given to the Paying Agent at the time and as
               provided in the form of Bond.  The  Bondowners'  Election  Notice
               delivered  to the Paying Agent at the time and as provided in the
               form of Bond shall be in  substantially  the form provided in the
               form of Bond.

                    As soon as practicable after receiving notice of a tender of
               Bonds  under this  Section,  the Paying  Agent  shall  notify the
               Remarketing  Agent,  the  Agent  and  the  Trustee  by  telephone
               promptly confirmed in writing of the amount of Tendered Bonds and
               the specified Purchase Date.

                    During  the time  Bonds are  issued  in the  book-entry-only
               system,  all Bondowners'  Election  Notices shall be given by the
               Beneficial  Owner in accordance with the procedures of DTC or its
               successor.  The  Remarketing  Agent and the Paying Agent shall be
               entitled  to rely on the  accuracy  of any  Bondowners'  Election
               Notice delivered to the Paying Agent.

                    (4) Mandatory Tender of Bonds.  Bonds in the Weekly Mode are
               subject to mandatory  tender for purchase as provided in the form
               of Bond and in Section 2.11 hereof.

                    (5)  Interest  Rate  Periods for Bonds in Weekly  Mode.  The
               Interest  Rate  Period  for  Bonds in a Weekly  Rate  Mode  shall
               commence on Wednesday of each week and end on the next  following
               Tuesday;  except that (a) in the case of a Conversion of Bonds to
               a Weekly Mode from a different Mode, the Interest Rate Period for
               such Bonds shall  commence on the last  Interest  Payment Date in
               respect of the immediately preceding Interest Rate Period and end
               on  the  next  following  Tuesday;  and  (b)  in  the  case  of a
               Conversion of Bonds from a Weekly Mode to a different  Mode,  the
               last  Interest  Rate  Period for such Bonds  prior to  Conversion
               shall end on the last day immediately preceding the Conversion.

                    (D) Monthly Mode.

                    (1)  Determination  of Monthly Rates. The Monthly Rate shall
               be the rate of interest  determined by the Remarketing  Agent for
               each  Interest  Rate  Period,  to be the lowest rate which in its
               judgment, on the basis of prevailing financial market conditions,
               would  permit  the sale of the Bonds in the  Monthly  Mode at par
               plus accrued interest on and as of the Effective Date, but not in
               excess of the Maximum Rate. The Remarketing Agent shall determine
               the initial  Monthly Rate on or before the date of  conversion to
               the Monthly  Mode,  which Rate shall remain in effect as provided
               in  this  Indenture.  Thereafter,  the  Remarketing  Agent  shall
               redetermine  the Monthly Rate for each  subsequent  Interest Rate
               Period.  The Monthly Rate in effect for each Interest Rate Period
               shall  be  determined  not  later  than  the  Business  Day  next
               preceding  the Effective  Date which shall be the first  Business
               Day of a month.  Each Monthly Rate will remain in effect  through
               the day preceding the first Business Day of the succeeding month.
               The  Remarketing  Agent  shall  notify  the  Paying  Agent of the
               Monthly Rate by Electronic  Notice not later than 2:00 p.m.,  New
               York City time,  on the Business Day  immediately  preceding  the
               Effective Date. The Paying Agent shall give written notice of the
               Monthly Rate to the Trustee and the Agent.

                    Each  determination and  redetermination of the Monthly Rate
               shall be conclusive and binding on the Issuer,  the Trustee,  the
               Paying Agent, the Company,  the Agent and the Bondowners.  If for
               any reason the  Remarketing  Agent fails to determine the Monthly
               Rate  for  any  Bond  or  if  for  any  reason   such  manner  of
               determination shall be determined to be invalid or unenforceable,
               the  Bond  shall  be  deemed  to be in a  Flexible  Mode  with an
               Interest Rate Period ending on the next  succeeding  day which is
               immediately followed by a Business Day.

                    (2)  Conversions  from the  Monthly  Mode.  The Bonds in the
               Monthly Mode or any portion of such Bonds may be converted on any
               Interest  Payment  Date at the  election  of the  Agent  from the
               Monthly  Mode  to  the  Daily,   Flexible,   Weekly,   Quarterly,
               Semiannual,  Multiannual  or Fixed Rate Mode as  provided  in the
               form of Bond, so long as no Event of Default  hereunder exists as
               certified  to the  Trustee  by the  Agent.  Written  notice  of a
               conversion  from the Monthly  Mode shall be given by the Agent to
               the Issuer, the Trustee,  the Paying Agent, the Remarketing Agent
               and the  Rating  Agencies  not  fewer  than 45 days  prior to the
               proposed  Conversion  Date,  which date shall be specified by the
               Agent in such notice.  Notice of a  conversion  of Bonds from the
               Monthly  Mode and the  mandatory  tender of Bonds for purchase on
               such  Conversion  Date shall be given to the owners of such Bonds
               as  provided in Section  2.02(D)(4)  hereof and the form of Bond.
               Conversions  to the Fixed  Rate Mode shall  also be  governed  by
               Section 2.02(H) hereof.

                    Notwithstanding  the  foregoing,  if  the  preconditions  to
               conversion to another Mode established by the preceding paragraph
               and  Section  2.02(K)  are not met by 10:30  a.m.,  New York City
               time,  on the  Conversion  Date,  the Paying Agent shall deem the
               proposed  conversion to have failed and shall immediately  notify
               the Trustee,  the Agent and the Remarketing  Agent, and the Bonds
               shall be  subject  to  mandatory  tender as  provided  in Section
               2.02(D)(4) hereof. In addition, the failed conversion shall cause
               the interest rate on the Bonds subject to such failed  conversion
               to immediately convert to the Flexible Mode with an Interest Rate
               Period  ending on the next  succeeding  day which is  immediately
               followed  by a Business  Day.  In such  event,  such Bonds  shall
               remain  subject to  mandatory  tender  pursuant  to Section  2.11
               hereof. In no event shall the failure of Bonds to be converted to
               another Mode for any reason be deemed to be, in and of itself, an
               Event of Default  under this  Indenture,  so long as the Purchase
               Price of all Bonds  required to be purchased is made available as
               provided above.

                    (3)  Bondowners'  Option to Tender  Bonds in  Monthly  Mode.
               Bonds in the Monthly Mode are subject to tender,  at the election
               of  the  owner  thereof,   in  the  manner  and  subject  to  the
               limitations described in the form of Bond. The owners of Tendered
               Bonds shall  receive on the Delivery  Date 100% of the  principal
               amount of the  Tendered  Bonds.  Accrued  interest  shall be paid
               separately,  and not as part of the Purchase  Price on such date.
               The  purchase of Tendered  Bonds  shall not  extinguish  the debt
               represented  by such Bonds which  shall  remain  Outstanding  and
               unpaid under this Indenture.
                                                       
                    The Paying Agent shall accept all  Tendered  Bonds  properly
               tendered  to it for  purchase as provided in the form of Bond and
               in this subsection (3); provided,  however, that the Paying Agent
               shall  not  accept  any  Tendered  Bonds and the  Purchase  Price
               therefor  shall not be paid if on the Purchase Date the principal
               of the Bonds shall have been accelerated pursuant to Section 6.02
               hereof and such acceleration shall not have been annulled.

                    The  Bondowners'  Election  Notice  delivered  to the Paying
               Agent at the time and as provided in the form of Bond shall be in
               substantially the form provided in the form of Bond.

                    As soon as practicable after receiving notice of a tender of
               Bonds  under this  Section,  the Paying  Agent  shall  notify the
               Remarketing  Agent,  the  Agent  and  the  Trustee  by  telephone
               promptly confirmed in writing of the amount of Tendered Bonds and
               the specified Purchase Date.

                    During  the time  Bonds are  issued  in the  book-entry-only
               system,  all Bondowners'  Election  Notices shall be given by the
               Beneficial  Owner in accordance with the procedures of DTC or its
               successor.  The Paying  Agent  shall be  entitled  to rely on the
               accuracy of any  Bondowners'  Election  Notice  delivered  to the
               Paying Agent.

                    (4) Mandatory Tender of Bonds. Bonds in the Monthly Mode are
               subject to mandatory  tender for purchase as provided in the form
               of Bond and in Section 2.11 hereof.

                    (E) Quarterly Mode.

                    (1)  Determination  of Quarterly  Rates.  The Quarterly Rate
               shall be the rate of interest determined by the Remarketing Agent
               for each Interest Rate Period, to be the lowest rate which in its
               judgment, on the basis of prevailing financial market conditions,
               would permit the sale of the Bonds in the  Quarterly  Mode at par
               plus accrued interest on and as of the Effective Date, but not in
               excess of the Maximum Rate. The Remarketing Agent shall determine
               the initial Quarterly Rate on or before the date of conversion to
               the  Quarterly  Mode.  Thereafter,  the  Remarketing  Agent shall
               redetermine the Quarterly Rate for each subsequent  Interest Rate
               Period.  The  Quarterly  Rate in effect  for each  Interest  Rate
               Period shall be  determined  not later than the Business Day next
               preceding the Effective Date. The Remarketing  Agent shall notify
               the Paying Agent of the Quarterly  Rate by Electronic  Notice not
               later than 2:00 p.m.,  New York City time,  on the  Business  Day
               immediately  preceding the Effective Date. The Paying Agent shall
               give written  notice of the Quarterly Rate to the Trustee and the
               Agent. Each  determination and  redetermination  of the Quarterly
               Rate shall be conclusive and binding on the Issuer,  the Trustee,
               the Paying Agent, the Company,  the Agent and the Bondowners.  If
               for any reason  the  Remarketing  Agent  fails to  determine  the
               Quarterly  Rate for any Bond or if for any reason  such manner of
               determination shall be determined to be invalid or unenforceable,
               the Quarterly  Rate Bond shall be deemed to be in a Flexible Mode
               with an Interest  Rate Period ending on the next  succeeding  day
               which is immediately followed by a Business Day.

                    (2)  Conversions  from the Quarterly  Mode. The Bonds in the
               Quarterly  Mode or any portion of such Bonds may be  converted on
               any  Interest  Payment Date at the election of the Agent from the
               Quarterly  Mode  to  the  Flexible,   Daily,   Weekly,   Monthly,
               Semiannual,  Multiannual  or Fixed Rate Mode as  provided  in the
               form of Bond, so long as no Event of Default  hereunder exists as
               certified  to the  Trustee  by the  Agent.  Written  notice  of a
               conversion from the Quarterly Mode shall be given by the Agent to
               the Issuer, the Trustee,  the Paying Agent, the Remarketing Agent
               and the  Rating  Agencies  not  fewer  than 45 days  prior to the
               proposed  Conversion  Date,  which date shall be specified by the
               Agent in such notice.  Notice of a  conversion  of Bonds from the
               Quarterly Mode and the mandatory  tender of Bonds for purchase on
               such  Conversion  Date shall be given to the owners of such Bonds
               as  provided in Section  2.02(E)(4)  hereof and the form of Bond.
               Conversions  to the Fixed  Rate Mode shall  also be  governed  by
               Section 2.02(H) hereof.

                    Notwithstanding  the  foregoing,  if  the  preconditions  to
               conversion to another Mode established by the preceding paragraph
               and  Section  2.02(K)  are not met by 10:30  a.m.,  New York City
               time,  on the  Conversion  Date,  the Paying Agent shall deem the
               proposed  conversion to have failed and shall immediately  notify
               the Trustee,  the Agent and the Remarketing  Agent, and the Bonds
               shall be  subject  to  mandatory  tender as  provided  in Section
               2.02(E)(4) hereof. In addition, the failed conversion shall cause
               the interest rate on the Bonds subject to such failed  conversion
               to immediately convert to the Flexible Mode with an Interest Rate
               Period  ending on the next  succeeding  day which is  immediately
               followed  by a Business  Day.  In such  event,  such Bonds  shall
               remain  subject to  mandatory  tender  pursuant  to Section  2.11
               hereof. In no event shall the failure of Bonds to be converted to
               another Mode for any reason be deemed to be, in and of itself, an
               Event of Default  under this  Indenture,  so long as the Purchase
               Price of all Bonds  required to be purchased is made available as
               provided above.

                    (3)  Bondowners'  Option to Tender Bonds in Quarterly  Mode.
               Bonds  in the  Quarterly  Mode  are  subject  to  tender,  at the
               election of the owner  thereof,  in the manner and subject to the
               limitations described in the form of Bond. The owners of Tendered
               Bonds shall  receive on the Delivery  Date 100% of the  principal
               amount of the  Tendered  Bonds.  Accrued  interest  shall be paid
               separately,  and not as part of the Purchase  Price on such date.
               The  purchase of Tendered  Bonds  shall not  extinguish  the debt
               represented  by such Bonds which  shall  remain  Outstanding  and
               unpaid under this Indenture.

                    The Paying Agent shall accept all  Tendered  Bonds  properly
               tendered  to it for  purchase as provided in the form of Bond and
               in this subsection (3); provided,  however, that the Paying Agent
               shall  not  accept  any  Tendered  Bonds and the  Purchase  Price
               therefor  shall not be paid if on the Purchase Date the principal
               of the Bonds shall have been accelerated pursuant to Section 6.02
               hereof and such acceleration shall not have been annulled.

                    The  Bondowners'  Election  Notice  delivered  to the Paying
               Agent at the time and as provided in the form of Bond shall be in
               substantially the form provided in the form of Bond.

                    As soon as practicable after receiving notice of a tender of
               Bonds  under this  Section,  the Paying  Agent  shall  notify the
               Remarketing  Agent,  the  Agent  and  the  Trustee  by  telephone
               promptly confirmed in writing of the amount of Tendered Bonds and
               the specified Purchase Date.

                    During  the time  Bonds are  issued  in the  book-entry-only
               system,  all Bondowners'  Election  Notices shall be given by the
               Beneficial  Owner in accordance with the procedures of DTC or its
               successor.  The Paying  Agent  shall be  entitled  to rely on the
               accuracy of any  Bondowners'  Election  Notice  delivered  to the
               Paying Agent.

                    (4) Mandatory  Tender of Bonds.  Bonds in the Quarterly Mode
               are subject to  mandatory  tender for purchase as provided in the
               form of Bond and in Section 2.11 hereof.

                    (F) Semiannual Mode.

                    (1)  Determination of Semiannual  Rates. The Semiannual Rate
               shall  be the  rate of  interest  determined  by the  Remarketing
               Agent, for each Interest Rate Period, to be the lowest rate which
               in its  judgment,  on the basis of  prevailing  financial  market
               conditions,  would permit the sale of the Bonds in the Semiannual
               Mode at par  plus  accrued  interest  on and as of the  Effective
               Date,  but not in excess of the  Maximum  Rate.  The  Remarketing
               Agent shall  determine the initial  Semiannual  Rate on or before
               the date of conversion to the Semiannual  Mode.  Thereafter,  the
               Remarketing  Agent shall redetermine the Semiannual Rate for each
               subsequent  Interest Rate Period.  The Semiannual  Rate in effect
               for each Interest Rate Period shall be determined  not later than
               the  Business  Day  next   preceding  the  Effective   Date.  The
               Remarketing Agent shall notify the Paying Agent of the Semiannual
               Rate by Electronic Notice not later than 2:00 p.m., New York City
               time,  on the Business Day  immediately  preceding  the Effective
               Date.   The  Paying  Agent  shall  give  written  notice  of  the
               Semiannual Rate to the Trustee and the Agent. Each  determination
               and  redetermination  of the Semiannual  Rate shall be conclusive
               and binding on the Issuer,  the Trustee,  the Paying  Agent,  the
               Company,  the Agent and the  Bondowners.  If for any  reason  the
               Remarketing  Agent fails to determine the Semiannual Rate for any
               Bond or if for any reason such manner of  determination  shall be
               determined  to be  invalid  or  unenforceable,  the Bond shall be
               deemed to be in a  Flexible  Mode with an  Interest  Rate  Period
               ending on the next  succeeding day which is immediately  followed
               by a Business Day.
                                                        
                    (2) Conversions  from the Semiannual  Mode. The Bonds in the
               Semiannual  Mode or any portion of such Bonds may be converted on
               any  Interest  Payment Date at the election of the Agent from the
               Semiannual  Mode  to  the  Flexible,   Daily,  Weekly,   Monthly,
               Quarterly, Multiannual or Fixed Rate Mode as provided in the form
               of Bond,  so long as no  Event of  Default  hereunder  exists  as
               certified  to the  Trustee  by the  Agent.  Written  notice  of a
               conversion  from the Semiannual  Mode shall be given by the Agent
               to the Issuer,  the Trustee,  the Paying Agent,  the  Remarketing
               Agent and the Rating Agencies not fewer than 45 days prior to the
               proposed  Conversion  Date,  which date shall be specified by the
               Agent in such notice.  Notice of a  conversion  of Bonds from the
               Semiannual Mode and the mandatory tender of Bonds for purchase on
               such  Conversion  Date shall be given to the owners of such Bonds
               as  provided in Section  2.02(F)(4)  hereof and the form of Bond.
               Conversions  to the Fixed  Rate Mode shall  also be  governed  by
               Section 2.02(H) hereof.

                    Notwithstanding  the  foregoing,  if  the  preconditions  to
               conversion to another Mode established by the preceding paragraph
               and  Section  2.02(K)  are not met by 10:30  a.m.,  New York City
               time,  on the  Conversion  Date,  the Paying Agent shall deem the
               proposed  conversion to have failed and shall immediately  notify
               the Trustee,  the Agent and the Remarketing  Agent, and the Bonds
               shall be  subject  to  mandatory  tender as  provided  in Section
               2.02(F)(4) hereof. In addition, the failed conversion shall cause
               the  interest  rate on the Bonds to  immediately  convert  to the
               Flexible  Mode with an Interest  Rate  Period  ending on the next
               succeeding day which is  immediately  followed by a Business Day.
               In such  event,  such Bonds  shall  remain  subject to  mandatory
               tender  pursuant to Section  2.11  hereof.  In no event shall the
               failure of Bonds to be  converted  to another Mode for any reason
               be deemed to be, in and of itself, an Event of Default under this
               Indenture, so long as the Purchase Price of all Bonds required to
               be purchased is made available as provided above.

                    (3) Bondowners'  Option to Tender Bonds in Semiannual  Mode.
               Bonds  in the  Semiannual  Mode are  subject  to  tender,  at the
               election of the owner  thereof,  in the manner and subject to the
               limitations described in the form of Bond. The owners of Tendered
               Bonds shall  receive on the Delivery  Date 100% of the  principal
               amount of the  Tendered  Bonds.  Accrued  interest  shall be paid
               separately,  and not as part of the Purchase  Price on such date.
               The  purchase of Tendered  Bonds  shall not  extinguish  the debt
               represented  by such Bonds which  shall  remain  Outstanding  and
               unpaid under this Indenture.

                    The Paying Agent shall accept all  Tendered  Bonds  properly
               tendered  to it for  purchase as provided in the form of Bond and
               in this subsection (3); provided,  however, that the Paying Agent
               shall  not  accept  any  Tendered  Bonds and the  Purchase  Price
               therefor  shall not be paid if on the Purchase Date the principal
               of the Bonds shall have been accelerated pursuant to Section 6.02
               hereof and such acceleration shall not have been annulled.
                     
                    The  Bondowners'  Election  Notice  delivered  to the Paying
               Agent at the time and as provided in the form of Bond shall be in
               substantially the form provided in the form of Bond.

                    As soon as practicable after receiving notice of a tender of
               Bonds  under this  Section,  the Paying  Agent  shall  notify the
               Remarketing  Agent,  the  Agent  and  the  Trustee  by  telephone
               promptly confirmed in writing of the amount of Tendered Bonds and
               the specified Purchase Date.

                    During  the time  Bonds are  issued  in the  book-entry-only
               system,  all Bondowners'  Election  Notices shall be given by the
               Beneficial  Owner in accordance with the procedures of DTC or its
               successor.  The Paying  Agent  shall be  entitled  to rely on the
               accuracy of any  Bondowners'  Election  Notice  delivered  to the
               Paying Agent.

                    (4) Mandatory Tender of Bonds.  Bonds in the Semiannual Mode
               are subject to  mandatory  tender for purchase as provided in the
               form of Bond and in Section 2.11 hereof.

                    (G) Multiannual Mode.

                    (1) Determination of Multiannual Rates. The Multiannual Rate
               shall be the rate of interest determined by the Remarketing Agent
               for each Interest Rate Period, to be the lowest rate which in its
               judgment, on the basis of prevailing financial market conditions,
               would  permit the sale of the Bonds with the same  Interest  Rate
               Period  in a  secondary  market  transaction  on  and  as of  the
               Effective Date, at a price equal to the principal  amount thereof
               plus accrued interest, but not in excess of the Maximum Rate. The
               Remarketing  Agent shall determine the initial  Multiannual  Rate
               and Interest  Rate Period on or before the date of  conversion to
               the Multiannual  Mode.  Thereafter,  the Remarketing  Agent shall
               redetermine  the Multiannual  Rate for each  subsequent  Interest
               Rate  Period  as  provided  herein  and  shall  redetermine  each
               subsequent  Interest Rate Period.  The Multiannual Rate in effect
               for each  Interest  Rate Period and the  duration of the Interest
               Rate Period shall be  determined  not later than two (2) Business
               Days prior to the Effective Date. The Effective Date shall be the
               first  Business  Day of a month if the  preceding  Interest  Rate
               Period is a Flexible,  Daily,  Weekly, or Monthly Rate Period and
               shall be the first day of a month if the preceding  Interest Rate
               Period is a Quarterly,  Semiannual,  or Multiannual  Rate Period.
               The Multiannual Rate will remain in effect until the first day of
               the month  following  the whole number of years  specified as the
               duration  of the  Interest  Rate  Period  for  the  Bonds  in the
               Multiannual Mode; provided that if the following Rate Period is a
               Flexible,  Daily, Weekly, or Monthly Rate Period, the Multiannual
               Rate  will  remain in effect  until the day  preceding  the first
               Business  Day of the month  following  the whole  number of years
               specified as the duration of the  Multiannual  Rate Period and if
               the following Rate Period is a Quarterly, Semiannual, Multiannual
               or Fixed Rate Period,  the  Effective  Date will remain in effect
               until the day preceding the first day of the month  following the
               whole number of years specified as the  Multiannual  Rate Period.
               The  Remarketing  Agent  shall  notify  the  Paying  Agent of the
               Multiannual  Rate and the  Interest  Rate  Period  by  Electronic
               Notice  not later than 2:00  p.m.,  New York City  time,  two (2)
               Business  Days  preceding the  Effective  Date.  The Paying Agent
               shall give written notice of the Multiannual  Rate to the Trustee
               and the Agent.  Each  determination  and  redetermination  of the
               Multiannual  Rate shall be conclusive  and binding on the Issuer,
               the Trustee,  the Paying  Agent,  the Company,  the Agent and the
               Bondowners.   If  the  Remarketing   Agent  fails  to  make  such
               determination  or  fails  to  announce  the  Multiannual  Rate as
               required with respect to any Bonds in the Multiannual Mode, or if
               for any reason such manner of  determination  shall be determined
               to be invalid or unenforceable,  the Bonds shall be automatically
               converted  to the  Flexible  Mode with an  Interest  Rate  Period
               ending on the next  succeeding day which is immediately  followed
               by a Business Day.

                    (2) Conversions from the Multiannual  Mode. The Bonds in the
               Multiannual Mode or any portion of such Bonds may be converted on
               any  Effective  Date  at the  election  of  the  Agent  from  the
               Multiannual  Mode  to  the  Daily,  Weekly,  Flexible,   Monthly,
               Quarterly,  Semiannual  or Fixed  Rate Mode and may be  converted
               within the  Multiannual  Mode to a new Interest  Rate Period with
               the same or a  different  length as provided in the form of Bond,
               so long as no Event of Default  hereunder  exists as certified to
               the Trustee by the Agent.  Written  notice of a change in Mode or
               Interest Rate Period within the  Multiannual  Mode shall be given
               by the Agent to the Issuer,  the Trustee,  the Paying Agent,  the
               Remarketing  Agent and the Rating Agencies not fewer than 45 days
               prior to the proposed  Conversion Date.  Conversions to the Fixed
               Rate Mode shall also be governed by Section 2.02(H) hereof.

                    Notwithstanding  the  foregoing,  if  the  preconditions  to
               conversion to another Mode established by the preceding paragraph
               and  Section  2.02(K)  are not met by 10:30  a.m.,  New York City
               time,  on the  Conversion  Date,  the Paying Agent shall deem the
               proposed  conversion to have failed and shall immediately  notify
               the Trustee,  the Agent and the  Remarketing  Agent and the Bonds
               shall  automatically  convert to a Flexible Mode with an Interest
               Rate  Period  ending  on  the  next   succeeding   day  which  is
               immediately followed by a Business Day. In such event, such Bonds
               shall remain subject to mandatory tender pursuant to Section 2.11
               hereof. In no event shall the failure of Bonds to be converted to
               another Mode or Interest  Rate Period for any reason be deemed to
               be, in and of itself,  an Event of Default under this  Indenture,
               so  long  as the  Purchase  Price  of all  Bonds  required  to be
               purchased is made available as provided above.

                    (3) Bondowners'  Option to Tender Bonds in Multiannual Mode.
               Bonds in the  Multiannual  Mode are  subject  to  tender,  at the
               election of the owner  thereof,  in the manner and subject to the
               limitations described in the form of Bond. The owners of Tendered
               Bonds shall  receive on the Delivery  Date 100% of the  principal
               amount of the  Tendered  Bonds.  Accrued  interest  shall be paid
               separately,  and not as part of the Purchase  Price on such date.
               The  purchase of Tendered  Bonds  shall not  extinguish  the debt
               represented  by such Bonds which  shall  remain  Outstanding  and
               unpaid under this Indenture.

                    The Paying Agent shall accept all  Tendered  Bonds  properly
               tendered  to it for  purchase as provided in the form of Bond and
               in this subsection (3); provided,  however, that the Paying Agent
               shall  not  accept  any  Tendered  Bonds and the  Purchase  Price
               therefor  shall not be paid if on the Purchase Date the principal
               of the Bonds shall have been accelerated pursuant to Section 6.02
               hereof and such acceleration shall not have been annulled.

                    The  Bondowners'  Election  Notice  delivered  to the Paying
               Agent at the time and as provided in the form of Bond shall be in
               substantially the form provided in the form of Bond.
                                                        
                    As soon as practicable after receiving notice of a tender of
               Bonds  under this  Section,  the Paying  Agent  shall  notify the
               Remarketing  Agent,  the  Agent  and  the  Trustee  by  telephone
               promptly confirmed in writing of the amount of Tendered Bonds and
               the specified Purchase Date.

                    During  the time  Bonds are  issued  in the  book-entry-only
               system,  all Bondowners'  Election  Notices shall be given by the
               Beneficial  Owner in accordance with the procedures of DTC or its
               successor.  The Paying  Agent  shall be  entitled  to rely on the
               accuracy of any  Bondowners'  Election  Notice  delivered  to the
               Paying Agent.

                    (4) Mandatory Tender for Purchase.  Bonds in the Multiannual
               Mode are subject to mandatory  tender for purchase as provided in
               the form of Bond and in Section 2.11 hereof.

                    (H) Fixed Rate Mode.

                    (1) Determination of Fixed Rate and Conversion to Fixed Rate
               Mode. The interest rate on all or any portion of the Bonds may be
               converted  by the Agent to the Fixed Rate as provided in the form
               of Bond and Sections  2.02(A),  (B),  (C),  (D), (E), (F) and (G)
               hereof. Written notice of conversion to the Fixed Rate Mode shall
               be given by the Agent to the  Issuer,  the  Trustee,  the  Paying
               Agent,  the  Remarketing  Agent and the Rating Agencies not fewer
               than 30 days prior to the proposed  Conversion Date. Upon receipt
               of the  notice  of  conversion  to the  Fixed  Rate Mode from the
               Agent,  the Remarketing  Agent shall determine the Fixed Rate not
               later than 12:00 noon,  New York City time,  on the  Business Day
               immediately  preceding the Conversion  Date. The Fixed Rate shall
               be the  lowest  rate  which in the  judgment  of the  Remarketing
               Agent, on the basis of prevailing  financial  market  conditions,
               would permit the sale of the Bonds being so converted at par plus
               accrued  interest as of the Conversion Date on the basis of their
               terms as converted.

                    On the date of determination  thereof, the Remarketing Agent
               shall  notify  the  Paying  Agent,  the Agent and the  Trustee by
               Electronic  Notice of the Fixed Rate.  The Trustee shall promptly
               notify the Issuer in writing of the Fixed Rate. The determination
               of the Fixed Rate shall be conclusive  and binding on the Issuer,
               the Trustee,  the Paying  Agent,  the Company,  the Agent and the
               Bondowners. The first Interest Payment Date of Bonds converted to
               the Fixed Rate  shall be the next June 1 or  December 1 after the
               Conversion  Date.  The Fixed Rate shall  become  effective on the
               Conversion Date.

                    Notwithstanding  the  foregoing,  if  the  preconditions  to
               conversion to the Fixed Rate Mode  established by this subsection
               and  Section  2.02(K)  are not met by 10:30  a.m.,  New York City
               time, on the Conversion Date, the Paying Agent shall  immediately
               notify the Trustee and the Agent by telephone  promptly confirmed
               in writing. Upon such notice, the Trustee shall deem the proposed
               conversion  to have  failed  and  shall  proceed  as  such  under
               Sections   2.02(A)(2),    2.02(B)(2),   2.02(C)(2),   2.02(D)(2),
               2.02(E)(2),   2.02(F)(2),   2.02(G)(2)  or   2.02(H)(2)   hereof,
               whichever is applicable.

                    (2)  Conversions  from the Fixed Rate Mode. The Bonds in the
               Fixed Rate Mode or any portion of such Bonds may be  converted on
               any  Effective  Date at the  election of the Agent from the Fixed
               Rate Mode to the Daily,  Weekly,  Flexible,  Monthly,  Quarterly,
               Semiannual,  Multiannual  or Fixed Rate Mode, so long as no Event
               of Default  hereunder  exists as  certified to the Trustee by the
               Agent.  Written  notice of a change in Mode shall be given by the
               Agent  to  the  Issuer,  the  Trustee,   the  Paying  Agent,  the
               Remarketing  Agent and the Rating Agencies not fewer than 45 days
               prior to the proposed  Conversion Date.  Conversions to the Fixed
               Rate Mode shall also be governed by Section 2.02(H)(1) hereof.

                    Notwithstanding  the  foregoing,  if  the  preconditions  to
               conversion to another Mode established by the preceding paragraph
               and  Section  2.02(K)  are not met by 10:30  a.m.,  New York City
               time,  on the  Conversion  Date,  the Paying Agent shall deem the
               proposed  conversion to have failed and shall immediately  notify
               the Trustee,  the Agent and the  Remarketing  Agent and the Bonds
               shall  automatically  convert to a Flexible Mode with an Interest
               Rate  Period  ending  on  the  next   succeeding   day  which  is
               immediately followed by a Business Day. In such event, such Bonds
               shall remain subject to mandatory tender pursuant to Section 2.11
               hereof. In no event shall the failure of Bonds to be converted to
               another Mode for any reason be deemed to be, in and of itself, an
               Event of Default  under this  Indenture,  so long as the Purchase
               Price of all Bonds  required to be purchased is made available as
               provided above.

                    (3) Mandatory Tender of Bonds.  Bonds in the Fixed Rate Mode
               are subject to  mandatory  tender for purchase as provided in the
               form of Bond and in Section 2.11 hereof.

                    (I) Partial Conversions.

                    (1) General.  The Bonds may be converted in whole or in part
               to the Daily  Mode,  the  Flexible  Mode,  the Weekly  Mode,  the
               Monthly Mode,  the  Quarterly  Mode,  the  Semiannual  Mode,  any
               Interest  Rate Period in the  Multiannual  Mode or the Fixed Rate
               Mode  upon  compliance  with  the  conditions  set  forth in this
               Indenture.  In the event the Bonds are in (or are to be converted
               to) more than one Mode, the provisions  herein  relating to Bonds
               in a particular  Mode (or to be  converted to a particular  Mode)
               shall  apply  only to the Bonds in (or to be  converted  to) such
               Mode and, where necessary or  appropriate,  any reference in this
               Indenture  to the Bonds shall be  construed  to mean the Bonds in
               (or to be converted to) such Mode.

                    (2) Selection. In the event of any partial conversion of the
               Bonds to a new Mode, the Bonds to be converted  shall be selected
               by the Paying  Agent from the Bonds in the Mode  selected  by the
               Agent. The particular Bonds (or portions thereof) to be converted
               shall be selected  by lot by the Paying  Agent from all the Bonds
               in the Mode (or in the case of Bonds in the Multiannual Mode, the
               Interest Rate Period) from which Bonds are to be  converted.  The
               principal  amount of Bonds to be converted shall be determined so
               that all of the Bonds shall be in Authorized Denominations. Bonds
               (or portions  thereof) in the Daily Mode,  Weekly  Mode,  Monthly
               Mode, Quarterly Mode and Semiannual Mode shall be selected by lot
               and the selection of the Bonds to be converted  shall occur prior
               to the date  notice of  mandatory  tender  is sent by the  Paying
               Agent  to  the  Bondowners   pursuant  to  Sections   2.02(B)(4),
               2.02(C)(4), 2.02(D)(4), 2.02(E)(4) and 2.02(F)(4).

                    (3)  Amendments.  The  provisions  of this  Indenture may be
               amended to permit or facilitate partial  conversions of the Bonds
               without Bondowner consent in accordance with Section 9.01 hereof.

     (J) Notice to Registered Owners of Change in Mode. When a change in Mode is
to be  made,  or  upon  commencement  of a  new  Interest  Rate  Period  in  the
Multiannual  Mode,  the Paying  Agent will notify the  registered  owners of the
affected Bonds in the Daily Mode, Weekly Mode, Monthly Mode,  Quarterly Mode and
Semiannual  Mode at least 15 days, and will notify the registered  owners of the
affected  Bonds in the  Multiannual  Mode and Fixed  Rate Mode at least 30 days,
before the effective date of the change. The notice will state:

                    (1) that the Mode  will be  changed  or that a new  Interest
               Rate Period in the Multiannual Mode, will commence,

                    (2) the  effective  date or  dates  of the new rate or a new
               Interest Rate Period, as applicable, and

                    (3) that a mandatory  tender  will  result on the  Effective
               Date of the change as provided in the Indenture.

     (K) Change In Interest  Rate Mode - Opinion of Counsel;  Issuer Veto Right.
No (i)  conversion of Bonds to or from a Multiannual  Mode with an Interest Rate
Period of over one year,  including  for this  purpose the  conversion  to a new
Interest Rate Period in the Multiannual  Mode, or (ii) conversion to or from the
Fixed Rate Mode shall be effective unless on or prior to the Conversion Date the
Agent shall  provide  the Issuer,  the Paying  Agent,  the Bond  Insurer and the
Trustee with a Favorable  Opinion.  Furthermore,  all Conversions are subject to
veto by the Issuer,  which veto may not be  unreasonably  exercised  and must be
exercised  by the  Authorized  Issuer  Representative  within one hour after the
receipt of notice from the Agent of such change in interest  rate  determination
method by the sending of a  telephonic  notice,  confirmed  in  writing,  to the
Agent, the Trustee, and the Remarketing Agent.

for  value  received,  hereby  promises  to pay  (but  only  out of the  sources
hereinafter  mentioned) to the Registered  Owner set forth above,  or registered
assigns,  on the Maturity Date specified above, unless this Bond shall have been

mentioned) to the Registered Owner, or registered  assigns,  interest thereon at
the rate  determined as herein  provided from the most recent  Interest  Payment
Date (hereinafter defined) to which interest has been paid or duly provided for,
or if no  interest  has been paid or duly  provided  for,  from the  Issue  Date
(unless this Bond initially bears interest at the Fixed Rate, in which case from

Registered  Owner hereof in immediately  available funds upon  presentation  and
surrender  hereof at the Principal  Office of the Trustee or its  successor,  as

both  principal and interest in the Bond Register kept by the Bond Registrar and
may be transferred or exchanged,  subject to the further conditions specified in
the Indenture,  only upon surrender  hereof at the office of the Bond Registrar.
This  Bond is  payable  solely  from  the  sources  hereinafter  mentioned.  The
principal of, premium, if any, and interest on, and Purchase Price of, this Bond
are payable in lawful money of the United States of America.

         CAPITALIZED TERMS NOT OTHERWISE DEFINED HEREIN SHALL HAVE THE MEANINGS
SPECIFIED THEREFOR IN THE INDENTURE.

     THE BONDS SHALL BE DEEMED NOT TO  CONSTITUTE  A DEBT OF THE STATE OF TEXAS,
THE ISSUER, OR OF ANY OTHER POLITICAL CORPORATION, SUBDIVISION, OR AGENCY OF THE
STATE OR A PLEDGE OF THE FAITH AND CREDIT OF ANY OF THEM.  NO RECOURSE  SHALL BE
HAD FOR ANY CLAIM BASED ON THE AGREEMENT,  THE  INDENTURE,  OR THE BONDS AGAINST
ANY MEMBER,  OFFICER OR EMPLOYEE,  PAST, PRESENT OR FUTURE, OF THE ISSUER, OR OF
ANY SUCCESSOR BODY THERETO,  EITHER DIRECTLY OR THROUGH THE ISSUER,  OR ANY SUCH
SUCCESSOR BODY, UNDER ANY CONSTITUTIONAL PROVISION, STATUTE OR RULE OF LAW OR BY
THE ENFORCEMENT OF ANY ASSESSMENT OR PENALTY OR OTHERWISE. NEITHER THE FAITH AND
CREDIT  NOR THE TAXING  POWER OF THE STATE OF TEXAS,  THE  ISSUER,  OR ANY OTHER
POLITICAL CORPORATION,  SUBDIVISION,  OR AGENCY IS PLEDGED TO THE PAYMENT OF THE
PRINCIPAL OF, REDEMPTION  PREMIUM, IF ANY, OR INTEREST ON, OR PURCHASE PRICE OF,
THE BONDS.  THIS BOND IS A SPECIAL  REVENUE  OBLIGATION  OF THE  ISSUER  PAYABLE
SOLELY FROM THE SOURCES  DESCRIBED HEREIN AND THE HOLDER HEREOF SHALL NEVER HAVE
THE RIGHT TO DEMAND  PAYMENT FROM MONEYS  DERIVED BY TAXATION OR ANY REVENUES OF
THE ISSUER EXCEPT THE FUNDS PLEDGED TO THE PAYMENT HEREOF.

     This  Bond is  authorized  and  issued  under  and  pursuant  to  authority
conferred by the Issuer Act,  Chapter 30, Texas Water Code, as amended,  Chapter
383,  Texas Health and Safety Code,  as amended,  Article 717k,  Vernon's  Texas
Civil Statutes,  as amended, and Article 717q, Vernon's Texas Civil Statutes, as
amended  (collectively,  the "Acts"),  a  resolution  adopted by the Issuer (the
"Bond  Resolution")  and the  Indenture.  This Bond is one of a duly  authorized
issue of revenue bonds of the Issuer issued in the aggregate principal amount of
$63,300,000  designated "Red River Authority of Texas Pollution  Control Revenue
Refunding  Bonds  (West  Texas  Utilities  Company,  Public  Service  Company of
Oklahoma and Central Power and Light  Company  Oklaunion  Project)  Series 1996"
(the  "Bonds")  issued  under the  Indenture.  The Bonds are being issued by the
Issuer for the purpose of paying a portion of the costs of refunding $63,300,000
in aggregate  principal  amount of Red River Authority of Texas  Adjustable Rate
Pollution  Control Revenue Bonds (West Texas Utilities  Company,  Public Service
Company of  Oklahoma  and Central  Power and Light  Company  Oklaunion  Project)
Series 1984. The Indenture pledges  substantially all right,  title and interest
of the Issuer, in and to the Installment Payment Agreement,  dated as of July 1,
1996 (the  "Agreement"),  between  the Issuer and West Texas  Utilities  Company
("WTU"),  Public Service Company of Oklahoma ("PSO") and Central Power and Light
Company  ("CPL")  (collectively,  the  "Company")  and  Central  and South  West
Services,  Inc.  (the  "Agent"),  together  with all moneys  payable  thereunder
including  "Installment  Payments" to be made by the Company in amounts equal to
the principal of,  premium,  if any, and interest on and Purchase  Price of, the
Bonds,  when  due,  but  excluding  certain  payments  to the  Issuer  for fees,
expenses, and indemnification.

                                                        

     Notwithstanding  the  definition of the term  "Company" as meaning WTU, PSO
and CPL  collectively,  each of WTU,  PSO and CPL is liable  severally,  but not
jointly,  to make or pay, or cause to be made or paid, its Ownership  Percentage
of each  Installment  Payment or other  obligation  under the  Agreement  or the
Indenture,  and none of WTU, PSO or CPL is obligated to make or pay, or cause to
be made or paid, more than its Ownership  Percentage of each Installment Payment
or other obligation under the Agreement or more than its Ownership Percentage of
the aggregate amount of all Installment  Payments or other obligations under the
Agreement.

     "Ownership  Percentage" means the respective payment obligations of each of
WTU, PSO and CPL expressed as a percentage as set forth below:

                           WTU              70%
                           PSO              20%
                           CPL              10%

     Pursuant to the  Agreement,  such Ownership  Percentages  may be changed by
agreement  among WTU, PSO and CPL without  notice to, or the approval or consent
of, the holders of the Bonds;  provided that the aggregate Ownership  Percentage
of WTU, PSO and CPL will at all times equal 100%.

     FOR SO LONG AS THIS BOND IS HELD IN BOOK-ENTRY  FORM REGISTERED IN THE NAME
OF CEDE & CO. ON THE  REGISTRATION  BOOKS OF THE ISSUER KEPT BY THE TRUSTEE,  AS
BOND REGISTRAR,  THIS BOND, IF CALLED FOR PARTIAL  REDEMPTION IN ACCORDANCE WITH
THE INDENTURE, SHALL BECOME DUE AND PAYABLE ON THE REDEMPTION DATE DESIGNATED IN
THE NOTICE OF REDEMPTION  GIVEN IN ACCORDANCE WITH THE INDENTURE AT, AND ONLY TO
THE EXTENT OF, THE  REDEMPTION  PRICE,  PLUS ACCRUED  INTEREST TO THE  SPECIFIED
REDEMPTION  DATE;  AND THIS BOND SHALL BE PAID,  TO THE EXTENT SO REDEEMED,  (i)
UPON  PRESENTATION AND SURRENDER  THEREOF AT THE OFFICE SPECIFIED IN SUCH NOTICE
OR (ii) AT THE WRITTEN REQUEST OF CEDE & CO., BY CHECK OR DRAFT MAILED TO CEDE &
CO. BY THE  TRUSTEE OR BY WIRE  TRANSFER  TO CEDE & CO. BY THE TRUSTEE IF CEDE &
CO.  AS  BONDOWNER  SO  ELECTS.  IF,  ON THE  REDEMPTION  DATE,  MONEYS  FOR THE
REDEMPTION OF BONDS TO BE REDEEMED,  TOGETHER  WITH  INTEREST TO THE  REDEMPTION
DATE, SHALL BE HELD BY THE TRUSTEE SO AS TO BE AVAILABLE  THEREFOR ON SUCH DATE,
AND AFTER  NOTICE OF  REDEMPTION  SHALL HAVE BEEN GIVEN IN  ACCORDANCE  WITH THE
INDENTURE,  THEN,  FROM AND AFTER THE REDEMPTION  DATE, THE AGGREGATE  PRINCIPAL
AMOUNT OF THIS  BOND  SHALL BE  IMMEDIATELY  REDUCED  BY AN AMOUNT  EQUAL TO THE
AGGREGATE  PRINCIPAL  AMOUNT THEREOF SO REDEEMED,  NOTWITHSTANDING  WHETHER THIS
BOND HAS BEEN SURRENDERED TO THE TRUSTEE FOR CANCELLATION.

     If an Event of Default occurs,  the principal of all Bonds issued under the
Indenture may become due and payable upon the  conditions  and in the manner and
with the effect provided in the Indenture.

     No recourse shall be had for the payment of the  principal,  Purchase Price
or redemption  price of, premium,  if any, or interest on, this Bond, or for any
claim based hereon or on the Indenture, against any member, officer or employee,
past, present or future, of the Issuer or of any successor body, as such, either
directly  or  through  the  Issuer  or  any  such  successor  body,   under  any
constitutional  provision,  statute or rule of law, or by the enforcement of any
assessment or by any legal or equitable proceeding or otherwise.




Interest on the Bonds

     The Bonds shall accrue  interest at interest  rates and for  Interest  Rate
Periods as  determined  in  accordance  with the  applicable  provisions  of the
Indenture. The Bonds will be subject to conversion as herein provided.

                                                        
     Interest  on the Bonds in a  Flexible  Mode,  Daily  Mode,  Weekly  Mode or
Monthly Mode shall be payable on the applicable  Interest Payment Date as herein
described, computed on the basis of a 365 or 366-day year, as applicable for the
number of days  actually  elapsed  based on the calendar year in which such Rate
Period  commences.  The interest on the Bonds in a Fixed Rate Mode,  Multiannual
Mode,  Semiannual  Mode or  Quarterly  Mode shall be  payable on the  applicable
Interest  Payment Date as herein  described,  computed on the basis of a 360-day
year of twelve 30-day months.  While there exists an Event of Default under this
Indenture,  the interest  rate on the Bonds will be the rate on the Bonds on the
day before the Event of Default occurred.

     At the option of the Agent and subject to certain  conditions  provided for
in the Indenture,  including being subject to veto by the Issuer, which veto may
not  be  unreasonably  exercised,  all or a  portion  of the  Bonds  (a)  may be
converted or reconverted from time to time to or from the Daily Mode, the Weekly
Mode,  the  Monthly  Mode,  the  Quarterly  Mode,  the  Semiannual  Mode  or the
Multiannual  Mode,  which means that the Interest  Rate Period for Bonds in such
Mode is, respectively, one day, one week, one month, three months, six months or
one year or any multiple of one year, (b) may be converted or  reconverted  from
time to time to or from the Flexible  Mode,  and will have Interest Rate Periods
of from one to 270 days during the Flexible Mode as provided herein,  or (c) may
be  converted  to or from the Fixed Rate Mode;  provided,  however,  that in the
Multiannual  Mode the first Interest Rate Period  occurring after  conversion to
such Mode may be shorter  than the  applicable  multiple of one year as provided
herein.

     Each determination and  redetermination of interest rates and Interest Rate
Periods shall be made in  accordance  with the Indenture and shall be conclusive
and binding on the Issuer, the Trustee, the Paying Agent, the Company, the Agent
and the Bondowners. Any Bondowner may ascertain the rate of interest on its Bond
or Bonds, at any time by contacting the Paying Agent or the Remarketing Agent.

     Unless otherwise defined herein,  capitalized terms used in this Bond shall
have the meaning given them in the Indenture.  As used herein,  "premium"  shall
mean,  with respect to any amount payable on the Bonds,  the amount,  if any, by
which the redemption price thereof (exclusive of interest) exceeds the principal

     "Business  Day" means any day on which  commercial  banks located in all of
the cities in which the Principal  Offices of the Trustee,  the Paying Agent and
the  Remarketing  Agent are located are not  required  or  authorized  by law or
regulation  to remain  closed  and on which the New York Stock  Exchange  is not
closed.

     "Conversion Date" means the date on which a new Mode becomes effective with
respect to a Bond, and with respect to a Bond in the Multiannual  Mode, the date
on which a new Interest Rate Period for such Bond becomes effective.
 
     "Effective Date" means, with respect to a Bond (a) in the Daily,  Flexible,
Weekly, Monthly, Quarterly,  Semiannual and Multiannual Modes, the date on which
a new Interest Rate Period for that Bond takes effect and (b) in the Multiannual
or  Fixed  Rate  Mode,  any date on  which  such  Bond is  subject  to  optional
redemption.

     "Electronic   Notice"  means  notice  transmitted  through  a  time-sharing
terminal,  by  facsimile  transmission  or by telephone  (promptly  confirmed in
writing or by facsimile transmission).

     "Interest Rate Period" or " Rate Period"  means,  when used with respect to
any  particular  rate of  interest  for a Bond in the Daily,  Flexible,  Weekly,
Monthly, Quarterly, Semiannual or Multiannual Mode, the period during which such

purchased  pursuant to a mandatory  or optional  tender in  accordance  with the
provisions hereof.

     "Purchase Price" means,  with respect to a Bond on a Purchase date, a price
equal to par plus accrued  interest to the Purchase  Date;  provided that in the
event that the Purchase Date is an Interest  Payment Date for such Bond and such
Bond is not in the Flexible Mode,  accrued  interest will be paid separately and
not as a part of the Purchase Price on such date;  and further  provided that in
the event such Bond bears interest at a Multiannual or Fixed Rate and is subject
to  mandatory  tender  on a date on  which  the  Bond  is  subject  to  optional
redemption,  Purchase  Price shall  include any premium that would be payable on
the Purchase Date if such Bond were redeemed on the Purchase Date..

Flexible  Rate

     While the Bonds accrue  interest at Flexible Rates,  the Remarketing  Agent
shall determine the Flexible Rate and the Flexible Rate Period for each Bond and
such Flexible  Rate will remain in effect from and  including  the  commencement
date of the Flexible Rate Period selected for that Bond by the Remarketing Agent
to,  but not  including,  the last  date  thereof.  While  the  Bonds are in the
Flexible Mode,  Bonds may have successive  Interest Rate Periods of any duration
up to 270 days each and any Bond may accrue  interest at a rate and for a period
different from any other Bond. No Interest Rate Period may be established  which
exceeds such maximum Interest Rate Period or, if the Remarketing Agent has given
or  received  notice of any  conversion  to a  Multiannual  or Fixed  Rate,  the
remaining  number of days prior to the  Conversion  Date or, if the  Remarketing
Agent  has  given or  received  notice  of any  conversion  to a Daily,  Weekly,
Monthly,  Quarterly or Semiannual  Mode, the length of each Interest Rate Period
for each Bond in the Flexible Mode shall be determined by the Remarketing  Agent
to be either (A) that length of period that,  as soon as possible,  shall enable
the Interest Rate Periods for all Bonds to end on the day before the  Conversion
Date,  or (B) that  length of period  which,  based on the  Remarketing  Agent's
judgment,  will best promote an orderly  transition  to the next  Interest  Rate
Period.

Daily Rate

     While  the  Bonds  accrue  interest  at a Daily  Rate,  the  interest  rate
established for the Bonds will be effective from day to day until changed by the
Remarketing Agent in accordance with the Indenture.

Weekly Rate

     While the Bonds accrue  interest at a Weekly Rate,  the rate of interest on
the Bonds will be determined  weekly by the Remarketing Agent in accordance with
the Indenture to be effective for a seven day period  commencing on Wednesday of
the  week  of  such  determination.  (The  length  of  the  period,  the  day of
commencement  and  the  last  day of the  period  may  vary  in the  event  of a
conversion to or from a Weekly Mode.)

Monthly Rate

     While the Bonds accrue  interest at a Monthly Rate, the rate of interest on
the Bonds will be determined monthly by the Remarketing Agent in accordance with
the Indenture to be effective from the first Business Day of a month through the
day preceding the first Business Day of the succeeding month. (The length of the
period,  the day of commencement  and the last day of the period may vary in the
event of a conversion to or from a Monthly Mode.)

Quarterly Rate

on the Bonds will be determined quarterly by the Remarketing Agent in accordance
with the Indenture to be effective for a calendar  quarter,  commencing on March
1, June 1,  September 1 and  December  1. (The length of the period,  the day of
commencement  and  the  last  day of the  period  may  vary  in the  event  of a
conversion to or from a Quarterly Mode.)


Semiannual  Rate

     While the Bonds accrue interest at a Semiannual  Rate, the rate of interest
on the  Bonds  will be  determined  semiannually  by the  Remarketing  Agent  in
accordance with the Indenture to be effective for a six month period, commencing
on June 1 or December 1. (The length of the period,  the day of commencement and
the last day of the  period may vary in the event of a  conversion  to or from a
Semiannual Mode.)

Multiannual Rate

     While the Bonds accrue  interest at a Multiannual  Rate,  the interest rate
will be determined by the Remarketing  Agent in accordance with the Indenture to
remain  in  effect  for a term of one  year or any  whole  multiple  of one year
selected  by the Agent  provided  that the initial  Interest  Rate Period may be
shorter  than the  applicable  multiple  of one  year.  The  length  of any such
Interest  Rate Period  established  will remain in effect  until  changed by the
Agent, in accordance with the Indenture.

Fixed Rate

     Upon  conversion  to a Fixed  Rate,  the Bonds  shall bear  interest to the
Maturity Date set forth above or until  converted to a different Mode at a fixed
rate of interest  determined by the  Remarketing  Agent in  accordance  with the
Indenture. If initially issued at a Fixed Rate, the Bonds shall bear interest to
the Maturity Date set forth above or until  converted to a different Mode at the
Interest Rate set forth above.

Authorized Denominations

     Bonds  which  accrue  interest  at  a  Flexible  Rate  will  be  issued  in
denominations  of  $100,000  and any  integral  multiples  of  $1,000  in excess
thereof. Bonds which accrue interest at a Daily or Weekly Rate will be issued in
denominations  of $100,000 and whole  multiples  thereof;  provided  that if the
principal  amount of Bonds in the Daily or Weekly  Mode,  as the case may be, is
not evenly  divisible  by $100,000,  then the  remainder of such amount shall be
added to another Bond in the same Mode that is in a principal amount of $100,000
or any integral  multiples  thereof.  Bonds which accrue  interest at a Monthly,
Quarterly,  Semiannual,  Multiannual  or  Fixed  Rate  will  be  issued  in  the
denomination of $5,000 and whole multiples thereof.

Optional Tenders

     While this Bond accrues interest at a Daily,  Weekly,  Monthly,  Quarterly,
Semiannual or Multiannual  Rate, the Registered Owner of this Bond has the right
to tender this Bond for  purchase at the  principal  amount  hereof plus accrued
interest as follows:  (i) during a Daily Rate  Period on any  Business  Day upon
written notice,  telephonic  notice, or Electronic Notice to the Paying Agent on
the Purchase Date, (ii) during a Weekly Mode on any Business Day upon written or
Electronic  Notice to the Paying  Agent on a  Business  Day not fewer than seven
days  prior  to  the  Purchase  Date  or  (iii)  during  a  Monthly,  Quarterly,
Semiannual, or Multiannual Rate Period, on any Interest Payment Date, which also
must be an Effective  Date of a Rate Period,  upon written  notice to the Paying
Agent not less than fifteen days before the Purchase Date.

     As long as the book-entry  system is in effect,  the Beneficial  Owner of a
Bond  may  demand  purchase  of the  Bond (or  portion  thereof)  owned by it by
providing   notice  as  provided  above  through  the  Beneficial   Owner's  DTC
Participant;  provided  such notice shall be given by 10:00 a.m.,  New York City
time, on the date such notice is required to be given. If the book-entry  system
is not in effect,  the registered owner of this Bond may demand purchase of this
Bond (or portion thereof in Authorized Denominations) by providing notice to the
Paying Agent as provided above and  delivering  this Bond to the Paying Agent at
its Principal Office.

     If the  Registered  Owner of a Bond has  elected  to  tender  such Bond for
purchase,  such Registered  Owner shall be deemed to have agreed  irrevocably to
sell such Bond to any purchaser  determined in accordance with the provisions of
the Indenture on the date fixed for purchase at the Purchase  Price and any Bond
not delivered shall be deemed tendered (an  "Undelivered  Bond") and shall cease
to be Outstanding under the Indenture and no further interest shall accrue as of
the Purchase  Date.  Notice of tender of a Bond is  irrevocable.  All notices of
tender of Bonds  shall be made to the Paying  Agent in writing or by  Electronic
Notice  (or such  other  notice as may be  specified  by the  procedures  of The
Depository  Trust Company or its successor so long as this Bond is held in book-
entry form) at its Principal Office in substantially the form as provided in the
Form of  Bondholder's  Election  Notice  for Bonds  Subject to  Optional  Tender
attached  hereto or such other form of notice  satisfactory  to the Paying Agent
which sets forth the  principal  amount of Bonds to be  purchased,  the purchase
date on which such Bonds shall be  purchased,  the name,  address  and  taxpayer
identification  number of the Registered Owner and the payment  instructions for
the Purchase Price.  All deliveries of tendered Bonds,  including  deliveries of
Bonds  subject to  mandatory  tender,  shall be made to the Paying  Agent at its
Principal Office.

Mandatory Tenders

     While this Bond accrues  interest at a Flexible Rate,  this Bond is subject
to  mandatory  tender  on each  Effective  Date  applicable  to this Bond at the
Purchase Price.

     This Bond is subject to mandatory  tender on the effective date of a change
from one Mode to a different Mode (other than from a Daily Mode to a Weekly Mode
or a Weekly Mode to a Daily Mode) or a change from one  Interest  Rate Period to
an Interest Rate Period of different duration within the Multiannual Mode at the
Purchase Price.

     BY ACCEPTANCE OF THIS BOND,  THE  REGISTERED  OWNER HEREOF AGREES THAT THIS
BOND WILL BE  PURCHASED,  WHETHER OR NOT  SURRENDERED,  ON THE PURCHASE  DATE AS
DESCRIBED  ABOVE. IN SUCH EVENT,  THE REGISTERED OWNER OF THIS BOND SHALL NOT BE
ENTITLED TO RECEIVE ANY FURTHER  INTEREST  HEREON,  SHALL HAVE NO FURTHER RIGHTS
UNDER THIS BOND OR THE INDENTURE EXCEPT TO RECEIVE PAYMENT OF THE PURCHASE PRICE
HELD  THEREFOR,  AND SHALL  THEREAFTER  HOLD  THIS BOND AS AGENT FOR THE  PAYING
AGENT.
 
Payment of Purchase Price

     The Purchase Price for Bonds (except Bonds in the Multiannual  Mode,  which
shall be in clearinghouse  funds) is payable by wire or bank transfer within the
continental  United States in immediately  available funds from the Paying Agent
to the Registered Owner. If on any date this Bond is subject to mandatory tender
for purchase or is required to be  purchased  at the election of the  Registered
Owner, payment of the Purchase Price of this Bond to such Registered Owner shall
be made on the  Purchase  Date if  delivery  of this Bond is made prior to 11:00
a.m.,  New York City time,  on the Purchase  Date or on such later  Business Day
upon  which  delivery  of this Bond is made prior to 11:00  a.m.,  New York City
time.

     BY ACCEPTANCE OF THIS BOND,  THE  REGISTERED  OWNER HEREOF AGREES THAT THIS
BOND WILL BE  PURCHASED,  WHETHER OR NOT  SURRENDERED,  ON THE PURCHASE  DATE AS
DESCRIBED  ABOVE. IN SUCH EVENT,  THE REGISTERED OWNER OF THIS BOND SHALL NOT BE
ENTITLED TO RECEIVE ANY FURTHER  INTEREST  HEREON,  SHALL HAVE NO FURTHER RIGHTS
UNDER THIS BOND OR THE INDENTURE EXCEPT TO RECEIVE PAYMENT OF THE PURCHASE PRICE
HELD  THEREFOR,  AND SHALL  THEREAFTER  HOLD  THIS BOND AS AGENT FOR THE  PAYING
AGENT.
                                                        
     The initial  Remarketing  Agent under the Indenture is Morgan Stanley & Co.
Incorporated.  The  Remarketing  Agent may be changed at any time in  accordance
with the Indenture.

Written Notice of Mode or Interest Rate Period Change

     The Trustee  shall give  notice,  by first class  mail,  to the  Registered
Owners of all Bonds of the proposed conversion from one Mode to another Mode, or
the commencement of a new Interest Rate Period in the Multiannual Mode, at least
15 days before the proposed  Conversion  Date while the Bonds accrue interest at
Flexible, Daily, Weekly, Monthly,  Quarterly or Semiannual Rates and at least 30
days before the  proposed  Conversion  Date while the Bonds  accrue  interest at
Multiannual or Fixed Rates.

Interest Payment Dates

     While this Bond accrues interest at a Flexible Rate, interest is payable on
the first  Business Day after the last day of each Interest  Rate Period.  While
this Bond  accrues  interest  at Daily,  Weekly or Monthly  Rates,  interest  is
payable on the first  Business Day of each calendar  month  following a month in
which interest at such rate has accrued.  While this Bond accrues  interest at a
Quarterly  Rate,  interest  is payable on each March 1, June 1,  September 1 and
December 1. While this Bond accrues  interest at a  Semiannual,  Multiannual  or
Fixed Rate,  interest is payable on the first day of the immediately  succeeding
June or December after Conversion to such Mode and thereafter on each June 1 and
December 1.

     The Bonds are subject to optional redemption as follows:

                    (A) During any Daily, Flexible,  Weekly, Monthly,  Quarterly

               written  direction of the Agent delivered to the Trustee in whole

               principal  amount  thereof plus accrued  interest  thereon to the
               redemption date.

                    (B) During any Multiannual or Fixed Rate Mode other than the

               written  direction of the Agent delivered to the Trustee in whole
               or in part (and if in part in an Authorized  Denomination) on any

     [Insert  Redemption  Provisions for Initial Fixed Rate Mode Interest Period
from Approval Certificate]

     So long as any Bond is in the  Multiannual or Fixed Rate Mode, such Bond is
subject  to  mandatory  tender for  purchase  at the  Purchase  Price in lieu of
optional redemption at the election of the Agent.

Extraordinary Optional Redemption

     The Bonds are subject to redemption in whole on the next available Interest
Payment Date for which notice of redemption can be given, at a redemption  price
equal to the aggregate  principal  amount of the Bonds  Outstanding plus accrued
interest  thereon to the redemption date,  without premium,  upon receipt by the
Trustee of a written  notice from the Agent  stating  that any of the  following
events  has  occurred  within  the  preceding  270 days and that it  intends  to
exercise its option to effect the redemption of the Bonds as a whole:

                    (i) In the  reasonable  judgment  of the Agent  unreasonable
               burdens or excessive liabilities shall have been imposed upon the
               Issuer or the Company  with  respect to the Project or the Plant,
               including without  limitation (A) the imposition of any income or
               other  taxes  not  being  imposed  on  July  1,  1996  or (B) the
               imposition of any ad valorem  property or other taxes (other than
               ad valorem  property or other taxes being imposed on July 1, 1996
               upon  similarly   assessed   property   within  the  same  taxing
               jurisdiction);

                    (ii) The  Project or the Plant  shall  have been  damaged or
               destroyed to such extent that,  in the opinion of the Agent,  (A)
               within a period of six consecutive  months  following such damage
               or  destruction,  it is not  practicable or desirable to rebuild,
               repair or  restore  the same,  (B) the  Company  will be  thereby
               prevented  from carrying on its normal  operations of the Project
               or the Plant for a period  of six or more  consecutive  months or
               (C) the cost of  restoration  would exceed by  $1,500,000 or more
               the net proceeds of insurance thereon;

                    (iii) Title to, or  temporary  use of, all or  substantially
               all of the  Project or the Plant  shall have been taken under the

               labor,  services,  supplies (including fuel),  equipment or other
               property, facilities or things necessary for the operation of the
               Project  or the Plant  shall  have  occurred,  or  technological,
               regulatory or other changes shall have  occurred,  which,  in the
               opinion  of the  Agent,  render the  continued  operation  of the
               Project or the Plant uneconomic;

                    (v) Any court or administrative body shall enter a judgment,
               order or decree  requiring  any of WTU,  PSO or CPL to cease,  or
               dispose of, all or any substantial  part of its operations of the
               Project or the Plant to such extent  that,  in the opinion of the
               Agent,  any of WTU,  PSO or CPL is or will be  thereby  prevented
               from  carrying  on its normal  operations  of the  Project or the
               Plant for a period of six or more consecutive months; or

                    (vi) As a result of any  change in the  Constitution  of the
               State  of Texas  or the  Constitution  of the  United  States  of
               America or of any legislative or  administrative  action (whether
               state or federal) or of any final decree,  judgment,  or order of
               any court or administrative body (whether state or federal),  the
               obligations  of any of WTU, PSO or CPL under the Agreement  shall
               have become  unenforceable  or impossible of  performance  in any
               material respect in accordance with the intent and purpose of the
               parties as expressed in the Agreement.

Extraordinary Mandatory Redemption


                                                        

     The Bonds are subject to  mandatory  redemption  in whole or in part at any
time if such partial  redemption will preserve the exemption from federal income
taxation of interest on the remaining Bonds  Outstanding,  at a redemption price
equal to the principal  amount thereof  together with unpaid interest accrued to
the date fixed for  redemption,  and without  premium,  if (i) a final decree or
judgment of any federal court, in which the Agent  participates to the extent it
deems  sufficient,  or (ii) a final action by the Internal Revenue  Service,  in
proceedings in which the Agent  participates to the extent it deems  sufficient,
determines that the interest paid or payable on any such Bonds to other than, as
provided in the Code, a "substantial  user" of the Project or a "related person"
is or was includable in the gross income of the owner thereof for federal income
tax  purposes  under the Code,  as a result of the failure by any of WTU, PSO or
CPL to observe or perform any covenant,  condition,  or agreement on its part to
be  observed  or  performed  under  the  Agreement  or  the  inaccuracy  of  any
representation by any of WTU, PSO or CPL under the Agreement; provided, however,
that no decree or  judgment  by any  court or  action  by the  Internal  Revenue
Service shall be considered  final unless the Registered  Owner involved in such
proceeding  or action (A) gives the Agent and the Trustee  prompt  notice of the
commencement  thereof  and (B),  if the  Agent  agrees  to pay all  expenses  in
connection  therewith  and  to  indemnify  such  Registered  Owner  against  all
liabilities in connection therewith, offers the Agent the opportunity to control
the defense  thereof.  Any such redemption shall be made on a date determined by
the Trustee not more than 180 days after the time of such final decree, judgment
or  action.  The  Trustee  shall  give the  Issuer  and the  Agent not less than
forty-five days written notice of such date.

     Not less than 30 nor more than 60 days prior to any  redemption  date,  the
Trustee shall cause notice of the call for redemption,  identifying each Bond or
portion thereof to be redeemed,  given in the name of the Issuer,  to be sent by
first class mail  (except when DTC is the  Registered  Owner of all of the Bonds
and except for persons or entities  owning or  providing  evidence of  ownership
satisfactory  to the  Trustee  of a legal or  beneficial  ownership  in at least
$1,000,000 in principal amount of Bonds, in which cases,  certified mail) to the
Registered  Owner of each Bond to be redeemed at the address  shown on the books
kept by the Trustee as Bond Registrar; should any Bond called for redemption not
be presented for payment  within 30 days of the redemption  date  therefor,  the
Trustee  shall cause a second  notice of the call for  redemption to be given by
certified  mail within 60 days after the redemption  date.  Failure to give such
notice or any defect therein shall not affect the sufficiency or validity of any
proceedings for the redemption of any other Bond. By the date fixed for any such
redemption,  due provision shall be made with the Trustee for the payment of the
redemption  price of, and  interest  on, the Bonds to be redeemed on the date of
redemption. If notice of redemption is given and if due provision for payment of
the redemption price and interest is made, all as provided in the Indenture, the
Bonds or portions thereof which are to be redeemed shall not bear interest after
the date  fixed for  redemption,  and shall not be  entitled  to any  benefit or
security  under the Indenture,  except for the right of the Registered  Owner to
receive the  redemption  price thereof and accrued  interest  thereon out of the
funds provided for such payment.

     Notwithstanding  the  provisions of the foregoing  paragraph,  no notice of
redemption  is required to be given to the owner of any Bond which is subject to
mandatory tender on the date fixed for redemption.

     If at the  time  of  mailing  of  notice  of  any  optional  redemption  in
connection  with a refunding of the Bonds,  the Company shall not have deposited
with the  Trustee  moneys  sufficient  to  redeem  all of the Bonds  called  for
redemption,  such notice may state that it is  conditional in that it is subject
to the  deposit of the  proceeds of  refunding  bonds with the Trustee not later
than the  redemption  date,  and such notice  shall be of no effect  unless such
moneys are so deposited.

General Provisions

     The  Bonds  are all  issued  under  and  entitled  to the  benefits  of the
Indenture. Pursuant to the Indenture, the Issuer has pledged and assigned to the

Bonds are  issued  and  secured,  to all of which  provisions,  and to all other
provisions of the Indenture,  the  Registered  Owner hereof by the acceptance of
this Bond  assents.  The  Registered  Owner hereof shall never have the right to
demand  payment out of any funds  raised or to be raised by taxation or from any
source  whatsoever  except  the  Trust  Estate.  Except  for the lien on and the
assignment  and  pledge  of the  Trust  Estate,  no  property  of the  Issuer is
encumbered  by any lien or security  interest for the benefit of the  Registered
Owner of this Bond.

     The ownership of this Bond may be transferred (in Authorized Denominations)
only upon presentation and surrender of this Bond at the Principal Office of the
Trustee as Bond  Registrar  together  with an  assignment  duly  executed by the
Registered Owner hereof or his duly authorized  attorney-in-fact in such form as
shall be  satisfactory  to the  Trustee,  and  subject  to the  provisions  made
therefor in the  Indenture,  provided  that the Trustee shall not be required to
make any such  transfer  of any Bond  during the 10  Business  Days  immediately
preceding  the mailing of a notice of Bonds  selected  for  redemption  or, with
respect to a Bond,  after such Bond or any portion thereof has been selected for
redemption.  Bonds may be exchanged at the principal  corporate  trust office of
the Trustee or at the offices of the Trustee's Agent for other Bonds aggregating
a like principal amount.  Bonds issued in exchange for other Bonds may be issued
only in Authorized Denominations.  Any service charge made by the Trustee or the
Trustee's  Agent for any such  registration,  transfer or exchange  hereinbefore
referred to shall be paid by the Company.  The Trustee,  the Trustee's Agent, or
the Issuer may require  payment by the  Registered  Owner of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.  The
Issuer,  the Company,  the Agent,  the Trustee and the Trustee's Agent may treat
the person in whose name this Bond is  registered  as the absolute  owner hereof
for any  purpose,  whether or not this Bond would be  overdue,  and  neither the
Issuer,  the Company,  the Agent, the Trustee,  nor the Trustee's Agent shall be
affected by notice to the contrary.

     Provisions may be made for the payment of amounts  represented by the Bonds
as provided in the Indenture,  in which event all liability of the Issuer to the
Registered  Owners of the  applicable  Bonds for the payment of such Bonds shall
forthwith cease, terminate and be completely discharged,  and thereupon it shall
be the duty of the Trustee to hold such funds (but only for the period specified
and as provided in the Indenture),  without liability for interest thereon,  for
the benefit of the  Registered  Owners of such Bonds,  who shall  thereafter  be
restricted exclusively to such funds for any claims of whatever nature under the
Indenture or on, or with respect to, said Bonds.

     The Bonds are secured by the Indenture,  whereunder the Trustee  undertakes
to enforce the rights of the Registered Owners of the Bonds and to perform other
duties to the extent and under the conditions  stated in the Indenture.  In case
an Event of Default  shall occur,  the  principal of the Bonds then  Outstanding
may, and, under certain circumstances,  shall, be declared to be due and payable
immediately  upon the  conditions  and in the manner  provided in the Indenture.
Failure to pay  interest  on any Bond when due does not  constitute  an Event of
Default  until such  failure has  continued  for a period of one Business Day or
more,  except while the Bonds bear interest at a  Multiannual  Rate or the Fixed
Rate,  in which case until such failure has continued for a period of sixty days
or more. Under the circumstances  provided in the Indenture,  the Trustee may in
its discretion and upon written  request of the Registered  Owners of a majority
in aggregate  principal  amount of the Bonds then Outstanding  shall,  waive any
Event of Default and its consequences;  provided,  however,  that default in the
payment of the principal of, premium,  if any, or interest on, or Purchase Price
of, the Bonds may not be so waived.  The  Registered  Owners of the Bonds  shall
have no right to institute any action, suit or proceeding at law or in equity to
enforce the Indenture,  except as provided in the Indenture;  provided, however,
that nothing in the Indenture shall affect or impair the right of the Registered
Owner of any Bond to enforce the payment of the principal of,  premium,  if any,
and  interest on such Bond from the source and in the manner  herein  expressed.
Reference  is hereby made to the  Indenture  and the  Agreement  for  additional
provisions  with respect to the nature and extent of the  security,  the rights,
duties, and obligations of the Company,  the Agent, the Issuer, the Trustee, and
the owners of the Bonds,  the terms upon which the Bonds are issued and secured,
and the modification of any of the foregoing.

     The Issuer has reserved the right to amend the  Indenture.  Under some (but
not all)  circumstances  amendments  thereto  must also be  approved  by (a) the
Registered  Owners of at least a majority in aggregate  principal  amount of the
Outstanding  Bonds or (b) if less than all of the Bonds are in a particular Mode
and the amendment  affects only the Owners of Bonds in that Mode,  the Owners of
at least a majority in aggregate  principal  amount of the Outstanding  Bonds in
such Mode.

                                                        
     No recourse shall be had for the payment of the  principal,  Purchase Price
or redemption  price of, premium,  if any, or interest on, this Bond, or for any
claim based hereon or on the Indenture, against any member, officer or employee,
past, present or future, of the Issuer or of any successor body, as such, either
directly or through the Issuer or any such successor body, under any conditional
provision, statute or rule of law, or by the enforcement of any assessment of by
any legal or equitable proceeding or otherwise.

     This Bonds  shall not be valid or become  obligatory  for any purpose or be
entitled to any  security or benefit  under the  Indenture  until either (i) the
Certificate  of  Authentication  hereon shall have been signed by the Trustee as
Bond  Registrar,  or any  successor,  or (ii) a  manually  signed  Comptroller's
Registration Certificate has been attached hereto or endorsed hereon.

     It is hereby certified,  recited and declared that all acts, conditions and
things  required  to exist,  happen  and be  performed  precedent  to and in the
execution  and delivery of the Indenture and the issuance of this Bond do exist,
have happened and have been  performed in due time,  form and manner as required
by law;  and that the  issuance  of this  Bond and the issue of which it forms a
part,  together  with all other  obligations  of the Issuer,  does not exceed or
violate any constitutional or statutory limitation.

     IN WITNESS  WHEREOF,  the Issuer has caused this Bond to be executed in its
name by the manual or facsimile  signature of its  President and attested by the
manual or facsimile  signature of its Secretary,  all as of the date first above
written.

COMPTROLLER'S REGISTRATION CERTIFICATE: REGISTER NO.

     I  hereby  certify  that  this  bond  has been  examined,  certified  as to
validity,  and approved by the Attorney  General of the State of Texas, and that
this bond has been registered by the Comptroller of Public Accounts of the State
of Texas.

         Witness my signature and seal this

                                              ________________________________
                                                Comptroller of Public Accounts
                                                     of the State of Texas


     Section 2.04. Execution;  Limited Obligations.  The Bonds shall be executed
on behalf of the Issuer with the manual or facsimile  signature of the President
of the Issuer, and attested,  under a manual or facsimile impression of the seal
of the Issuer,  with the manual or facsimile  signature of the  Secretary of the
Issuer. All authorized facsimile signatures shall have the same force and effect
as manual signatures. A facsimile impression of the Issuer's seal shall have the
same force and effect as a manual impression.  In case any officer of the Issuer
whose signature or a facsimile  thereof appears on a Bond shall cease to be such
officer before the delivery of such Bond, such signature or such facsimile shall
nevertheless  be valid  and  sufficient  for all  purposes,  the same as if such
officer had remained in office until delivery.

     The Bonds are not and never shall become general obligations of the Issuer,
but are  limited  obligations  payable  by the  Issuer  solely and only from the
payments received under or with respect to the documents executed by the Company
(except to the extent paid out of moneys  attributable  to the proceeds  derived
from the sale of the Bonds or income from the temporary investment of such funds
or other funds held hereunder),  which amounts, together with any other security
provided herein, are hereby specifically  assigned and pledged to such purposes,
in the manner and to the extent provided  herein.  The Bonds shall be deemed not
to  constitute  a debt of the  State  of  Texas,  the  Issuer,  or of any  other
political  corporation,  subdivision,  or agency of the State or a pledge of the
faith and credit of any of them. No recourse shall be had for any claim based on
the  Agreement,  the  Indenture,  or the Bonds  against any  member,  officer or
employee,  past,  present or future,  of the Issuer,  or of any  successor  body
thereto,  either  directly or through the Issuer,  or any such  successor  body,
under any constitutional provision, statute or rule of law or by the enforcement
of any  assessment or penalty or  otherwise.  Neither the State of Texas nor any
political  corporation,  subdivision,  or agent or the  State of Texas  shall be
obligated to pay the Bonds and neither the faith and credit nor the taxing power
of the State of Texas or any other political corporation, subdivision, or agency
is pledged to the payment of the principal of,  redemption  premium,  if any, or
interest  on, or Purchase  Price of, the Bonds.  This Bond is a special  revenue
obligation of the Issuer  payable solely from the sources  described  herein and
the holder  hereof  shall  never have the right to demand  payment  from  moneys
derived by taxation or any  revenues of the Issuer  except the funds  pledged to
the payment hereof.

     Section 2.05.  Conditions  Precedent to Delivery of Bonds;  Authentication.
The Issuer shall  execute and deliver the Bonds to the Trustee,  and the Trustee
shall, upon receipt by the Trustee of the purchase price for the Bonds,  deliver
the  Bonds  to the  initial  purchasers  thereof.  Prior  to and as a  condition
precedent to the  delivery of the Bonds there shall be filed with and  delivered
to the Trustee:

                    (i) a certified copy of the Bond Resolution;

                    (ii) original executed  counterparts of this Indenture,  the
               Approval Certificate, and the Agreement;

                    (iii)  a  written  order  of  the  Issuer,  directed  to the
               Trustee,  instructing  the  Trustee to  deliver  the Bonds to the
               initial  purchasers  thereof  upon payment to the Trustee for the
               account of the Issuer of the sum specified in such written order;
               and

                    (iv) an opinion of Bond Counsel  substantially to the effect
               that (A) the Bonds  constitute  legal,  valid and binding limited
               obligations of the Issuer,  enforceable in accordance  with their
               terms,   subject   to   bankruptcy,    insolvency,    moratorium,
               reorganization  and other  similar laws  affecting  the rights of
               creditors   and  to  the  exercise  of  judicial   discretion  in
               accordance with general principles of equity and (B) the interest
               on the Bonds is excludable  from gross income for Federal  income
               tax purposes  under  existing  statutes,  regulations,  published
               rulings and judicial  decisions,  except for interest on any Bond
               for any period  during which such Bond is held by a  "substantial
               user" of any  facilities  financed with the proceeds of the Bonds
               or a "related  person," as such terms are used in Section  147(a)
               of the Code, and other customary exclusions.

     No Bond shall be valid or  obligatory  for any  purpose or  entitled to any
security  or  benefit  under  this  Indenture  unless  and  until  either  (i) a
certificate of  authentication on such Bond shall have been duly executed by the
Trustee or (ii) a Comptroller's Registration Certificate attached to or endorsed
on such Bond has been duly executed. Such executed certificate of the Trustee or
Comptroller's  Registration  Certificate  upon any such Bond shall be conclusive
evidence that such Bond has been authenticated or registered and delivered under
this Indenture. The certificate of authentication on any Bond shall be deemed to
have  been  executed  by the  Trustee  if  signed by an  authorized  officer  or
signatory of the Trustee, but it shall not be necessary that the same officer or
signatory sign the certificates of authentication on all Bonds issued hereunder.

     Section 2.06. Redemption of Bonds. The Bonds shall be subject to redemption
by the Issuer prior to maturity only as follows:

                    (a)  Extraordinary  Optional  Redemption of Bonds. The Bonds
               are subject to redemption in whole on the next available Interest
               Payment Date for which notice of  redemption  can be given,  at a
               redemption  price equal to the aggregate  principal amount of the
               Bonds outstanding plus accrued interest thereon to the redemption
               date,  without premium,  upon receipt by the Trustee of a written
               notice from the Agent  stating that any of the  following  events
               has occurred  within the preceding 270 days and that it therefore
               intends to exercise its option to effect the  redemption of Bonds
               in whole:

                    (i) In the  reasonable  judgment  of the Agent  unreasonable
               burdens or excessive liabilities shall have been imposed upon the
               Issuer or the Company  with  respect to the Project or the Plant,
               including without  limitation (A) the imposition of any income or
               other  taxes  not  being  imposed  on  July  1,  1996  or (B) the
               imposition of any ad valorem  property or other taxes (other than
               ad valorem  property or other taxes being imposed on July 1, 1996
               upon  similarly   assessed   property   within  the  same  taxing
               jurisdiction);

                    (ii) The  Project or the Plant  shall  have been  damaged or
               destroyed to such extent that,  in the opinion of the Agent,  (A)
               within a period of six consecutive  months  following such damage
               or  destruction,  it is not  practicable or desirable to rebuild,
               repair or  restore  the same,  (B) the  Company  will be  thereby
               prevented  from carrying on its normal  operations of the Project
               or the Plant for a period  of six or more  consecutive  months or
               (C) the cost of  restoration  would exceed by  $1,500,000 or more
               the net proceeds of insurance thereon;

                    (iii) Title to, or  temporary  use of, all or  substantially
               all of the  Project or the Plant  shall have been taken under the
               exercise of the power of eminent domain;

                    (iv)  Changes in the  economic  availability  of  materials,
               labor,  services,  supplies (including fuel),  equipment or other
               property, facilities or things necessary for the operation of the
               Project  or the Plant  shall  have  occurred,  or  technological,
               regulatory or other changes shall have  occurred,  which,  in the
               opinion  of the  Agent,  render the  continued  operation  of the
               Project or the Plants uneconomic;

                    (v) Any court or administrative body shall enter a judgment,
               order or decree  requiring  any of WTU,  PSO or CPL to cease,  or
               dispose of, all or any substantial  part of its operations of the
               Project or the Plant to such extent  that,  in the opinion of the
               Agent,  any of WTU,  PSO or CPL is or will be  thereby  prevented
               from  carrying  on its normal  operations  of the  Project or the
               Plant for a period of six or more consecutive months; or

                    (vi) As a result of any  change in the  Constitution  of the
               State  of Texas  or the  Constitution  of the  United  States  of
               America or of any legislative or  administrative  action (whether
               state or federal) or of any final decree,  judgment,  or order of
               any court or administrative body (whether state or federal),  the
               obligations  of any of WTU, PSO or CPL under the Agreement  shall
               have become  unenforceable  or impossible of  performance  in any
               material respect in accordance with the intent and purpose of the
               parties as expressed in the Agreement.

                    (b) Optional  Redemption.  The Bonds are subject to optional
               redemption as follows:

                    (i) During any Daily, Flexible,  Weekly, Monthly,  Quarterly
               or  Semiannual  Mode,  the Bonds in such Mode shall be subject to
               redemption  prior to  maturity  at the option of the Issuer  upon
               written direction of the Agent delivered to the Trustee, in whole
               or in part (and if in part in an Authorized  Denomination) on any
               Interest  Payment Date applicable to the Bonds in such Mode, at a
               redemption  price  equal to the  principal  amount  thereof  plus
               accrued interest thereon to the redemption date.

                    (ii) During any Multiannual or Fixed Rate Mode, the Bonds in
               such Mode shall be subject to redemption prior to maturity at the
               option  of  the  Issuer  upon  written  direction  of  the  Agent
               delivered to the Trustee,  in whole or in part (and if in part in
               an Authorized Denomination) on any Business Day after the No-Call
               Period  described  below,  at  the  following  redemption  prices
               (expressed as  percentages  of the principal  amount of the Bonds
               called for  redemption)  plus accrued  interest to the date fixed
               for redemption:

     Notwithstanding  the foregoing,  if the Bonds  initially bear interest at a
Multiannual Rate or a Fixed Rate, the redemption  schedule shall be as set forth
in the Approval  Certificate.  In connection  with a Conversion  with respect to
Bonds  to  bear  interest  at  the  Multiannual  or  Fixed  Interest  Rate,  the
Remarketing  Agent,  upon the  request  of the Agent  (which  request  shall not
unreasonably  be refused) and in order to achieve the lowest rate which,  in the
judgment of the Remarketing  Agent, on the basis of prevailing  financial market
conditions,  would permit the sale of the Bonds so converted at par plus accrued
interest as of the Conversion Date, may deliver to the Issuer and the Trustee an
alternative  redemption  schedule to that shown above,  provided  that the Agent
delivers  to the  Issuer,  the  Remarketing  Agent and the  Trustee a  Favorable
Opinion with respect to the  alternative  schedule of redemption.  Prior to such
Conversion,  the Trustee  shall  determine  the optional  redemption  provisions
applicable to the Bonds in such Modes,  and such provisions shall be inserted in
the form of Bond.  After the  Conversion  Date  succeeding  the delivery of such
alternative  schedule and Favorable  Opinion during any Mode, the Bonds shall be
subject to  redemption  in accordance  with the  provisions of such  alternative
schedule.

     So long as any Bond is in the  Multiannual or Fixed Rate Mode, such Bond is
subject to mandatory  tender in lieu of optional  redemption  at the election of
the Agent as provided in Section 2.11 hereof.

                    (c)  Extraordinary  Mandatory  Redemption.   The  Bonds  are
               subject to mandatory  redemption  in whole or in part at any time
               if such  partial  redemption  will  preserve the  exemption  from
               federal  income  taxation  of  interest  on the  remaining  Bonds
               Outstanding,  at a redemption price equal to the principal amount
               thereof  together with unpaid interest  accrued to the date fixed
               for  redemption,  and without  premium,  if (i) a final decree or
               judgment of any federal court, in which the Agent participates to
               the extent it deems suffi-  cient,  or (ii) a final action by the
               Internal  Revenue  Service,  in  proceedings  in which  the Agent
               participates to the extent it deems  sufficient,  determines that
               the interest  paid or payable on any such Bonds to other than, as
               provided in the Code,  a  "substantial  user" of the Project or a
               "related  person" is or was includable in the gross income of the
               owner thereof for federal  income tax purposes under the Code, as
               a result of the  failure by any of WTU,  PSO or CPL to observe or
               perform any covenant,  condition,  or agreement on its part to be
               observed or performed  under the  Agreement or the  inaccuracy of
               any representation by any of WTU, PSO or CPL under the Agreement;
               provided,  however,  that no decree or  judgment  by any court or
               action by the Internal  Revenue Service shall be considered final
               unless the Registered Owner involved in such proceeding or action
               (A) gives the Agent and the Trustee  prompt written notice of the
               commencement  thereof  and (B),  if the  Agent  agrees to pay all
               expenses in connection therewith and to indemnify such Registered
               Owner against all liabilities in connection therewith, offers the
               Agent the  opportunity to control the defense  thereof.  Any such
               redemption  shall be made on a date determined by the Trustee not
               more than 180 days after the time of such final decree,  judgment
               or action.  The  Trustee  shall give the Issuer and the Agent not
               less than forty-five days written notice of such date.

     Section 2.07. Notice of Redemption.  Not less than thirty (30) days or more
than  sixty  (60) days  prior to any date  fixed for  redemption  of Bonds,  the
Trustee  shall  give  notice of any  redemption  by sending  such  notice by (i)
first-class mail to the Owner of each Bond to be redeemed in whole or in part at
the address shown on the  Registration  Books,  (ii) by certified  mail,  return
receipt requested,  to DTC (so long as it owns all the Bonds), and upon request,
to any person or entities which provide evidence  acceptable to the Trustee that
such  person  has a legal  or  beneficial  interest  in at least  $1,000,000  in
principal  amount of the Bonds,  and (iii) by  certified  mail,  return  receipt
requested, or by overnight delivery,  received by the registered depositories at
least two (2) days prior to the  general  publication  date for such  redemption
notices  and to be  received  by at least  two (2) of the  national  information
services  that  disseminate  bond  redemption  notices on or before the  general
mailing  date for such  notices;  provided,  however,  that the failure to send,
mail, or receive such notice  described  above,  or any defect therein or in the
sending  or  mailing  thereof,  with  respect  to any Bond  shall not affect the
validity or  effectiveness  of the  proceedings  for the redemption of any other
Bond.  In  addition,  within  sixty  (60)  days  after  the  redemption  date an
additional redemption notice shall be sent to any Owner of the Bonds who has not
surrendered Bonds for redemption during the thirty (30) day period following the
redemption  date and to any  person  or  entities  having  legal  or  beneficial
ownership  interest in at least  $1,000,000  in  principal  amount of such Bonds
which have not been surrendered.  All notices of redemption shall state: (i) the
redemption date, (ii) the redemption price, (iii) the identification,  including
complete  designation  (including  series)  and issue  date of the Bonds and the
CUSIP number,  certificate  number (and in the case of partial  redemption,  the
respective principal amounts), interest rates and maturity dates of the Bonds to
be redeemed,  (iv) that on the redemption date the redemption  price will become
due and payable upon each such Bond,  and that  interest  thereon shall cease to
accrue from and after said date, and (v) the name and address of Trustee and any
Paying  Agent for such  Bonds,  including  the place  where such Bonds are to be
surrendered for payment of the redemption price therefor.

     Upon  written  request  of any  Owner,  or of any  person or  entity  which
provides  evidence  acceptable  to the Trustee  that such person or entity has a
legal or  beneficial  interest in Bonds in an aggregate  principal  amount of at
least $1,000,000,  the Trustee shall send an additional copy of any notice to be
given to such Owner,  person or entity by the  Trustee  under the  Indenture  by
first-class mail to a second address specified by such Owner,  person or entity.
Any such  additional  notices  shall be given  simultaneously  with the original
notices.

     Section 2.08.  Redemption Payments;  Effect of Call for Redemption.  On the
date fixed for redemption of any Bond, funds for the payment thereof shall be on
deposit in the Bond Fund representing moneys deposited or caused to be deposited
by the Company  with the  Trustee,  and the  Trustee  hereby is  authorized  and
directed  to apply  such funds to the  payment  of each Bond or portion  thereof
called for redemption,  together with accrued interest thereon to the redemption
date and any  required  premium.  If at the time of  mailing  of  notice  of any
optional  redemption  in  connection  with a refunding  of the Bonds the Company
shall not have deposited with the Trustee moneys sufficient to redeem all of the
Bonds called for  redemption,  such notice may state that it is  conditional  in
that it is subject to the deposit of the  proceeds of  refunding  bonds with the
Trustee  not later than the  redemption  date,  and such  notice  shall be of no
effect  unless  such  moneys are so  deposited.  On the date so  designated  for
redemption,  notice  having  been given in the  manner and under the  conditions
hereinabove provided, any Bond or portion thereof so called for redemption shall
become and be due and payable at the redemption  price provided for herein;  and
if, in accordance  with the  provisions of Article V hereof,  sufficient  moneys
and/or  Government  Obligations,  the  principal  of, and  interest on, which at
maturity will provide sufficient moneys at the times required for payment of the
redemption  price and accrued  interest to the redemption  date are then held by
the  Trustee  in trust for the  Owners of every  Bond or  portion  thereof to be
redeemed,  interest on each such Bond or portion so called for redemption  shall
cease to accrue and each such Bond or portion thereof shall cease to be entitled
to any benefit or security under this Indenture, and the Owner of each such Bond
or portion  thereof  shall have no rights in respect  thereof  except to receive
payment of the  redemption  price  thereof and accrued  interest  thereon to the
redemption date from such moneys and/or Government Obligations.

     Section 2.09.  Partial Redemption . If fewer than all of the Bonds shall be
called for redemption,  the Agent may designate the principal amount of Bonds in
each Mode to be  redeemed,  and the Bonds to be  redeemed  in each Mode shall be
selected by lot by the Trustee from among all Outstanding Bonds in such Mode for
this purpose, each minimum increment of Authorized Denominations  represented by
any Bond shall be considered a separate Bond for purposes of selecting the Bonds
to be  redeemed.  If it is  determined  that  one or more,  but not all,  of the
minimum increments of Authorized Denominations  represented by any Bond is to be
called for  redemption,  then,  upon notice of  intention to redeem such minimum
increments of  Authorized  Denominations  of such Bond,  the Owner of such Bond,
upon  surrender  of such Bond to the  Trustee  for  payment to such Owner of the
redemption  price or the  principal  amount of such Bond called for  redemption,
shall be  entitled  to  receive a new Bond or Bonds in the  aggregate  principal
amount of the unredeemed balance of the principal amount of such Bond. New Bonds
representing the unredeemed  balance of the principal amount of such Bonds shall
be issued to the Owner thereof without a charge therefor.

                                                        
     If the  owner  of any  Bond of a  denomination  greater  than  the  minimum
increment  of  Authorized  Denominations  shall fail to present such Bond to the
Trustee for payment and exchange as  aforesaid,  such Bond shall,  nevertheless,
become due and  payable on the date  fixed for  redemption  to the extent of the
minimum  increments of Authorized  Denominations  called for redemption  (and to
that extent only),  and,  after the date fixed for  redemption,  interest  shall
cease to accrue on such principal amount called for redemption.

     Section 2.10. Remarketing and Purchase.

                    (a)   Remarketing  of  Tendered  Bonds.   Unless   otherwise
               instructed by the Agent,  the  Remarketing  Agent shall offer for
               sale and use its best efforts to find purchasers for all Bonds or
               portions  thereof  for which  notice of tender has been  received
               pursuant hereto or which are subject to mandatory  tender.  While
               the Bonds are in book-  entry only form,  the  Remarketing  Agent
               will make  payment for the Purchase  Price for tendered  Bonds in
               accordance  with  the  procedures  established  by  DTC.  If  the
               book-entry only system is not in effect, the terms of any sale by
               the  Remarketing  Agent  shall  provide  for the  payment  of the
               Purchase Price for tendered Bonds by the Remarketing Agent to the
               Paying Agent (i) in immediately available funds at or before 3:00
               p.m.,  New York City time,  on the Purchase  Date, in the case of
               Bonds accruing  interest at Flexible  Rates,  (ii) in immediately
               available  funds at or before 4:00 p.m.,  New York City time,  on
               the  Purchase  Date,  in the case of Bonds  accruing  interest at
               Daily Rates,  Weekly Rates,  Monthly  Rates,  Quarterly  Rates or
               Semiannual  Rates, and (iii) in clearinghouse  funds at or before
               12:00 noon, New York City time, on the Purchase Date, in the case
               of bonds accruing  interest at  Multiannual  or Fixed Rates.  The
               Remarketing Agent shall not sell any Bond as to which a notice of
               conversion from one type of Rate Period to another or as to which
               a notice of redemption  has been given by the Trustee  unless the
               Remarketing Agent has advised the person to whom the sale is made
               of the conversion or redemption,  as applicable.  The Remarketing
               Agent shall not  remarket  any Bonds  pursuant to this Section if
               the  Remarketing  Agent  has  received  notice  that an  Event of
               Default  shall have  occurred and is  continuing  hereunder  with
               respect to the Bonds.

                    (b) Purchase of Tendered Bonds.

                    (i) Notice.  At or before 3:00 p.m.,  New York City time, on

               of Bonds accruing interest at Daily, Weekly,  Flexible,  Monthly,
               Quarterly or Semiannual  Rates), the Remarketing Agent shall give
               Electronic  Notice  to the  Trustee  of the  principal  amount of
               tendered  Bonds as to  which  the  Remarketing  Agent  has  found
               purchasers.  Not later than 4:00 p.m. for Bonds bearing  interest
               at  Multiannual  or Fixed  Rates (or 11:45  a.m.,  in the case of
               Bonds  accruing  interest at Daily,  Weekly,  Flexible,  Monthly,
               Quarterly or Semiannual  Rates ), New York City time, on the date
               of  receipt  of such  notice the  Trustee  shall give  Electronic
               Notice  to  the  Paying  Agent  and  the  Agent,  specifying  the
               principal  amount of tendered  Bonds as to which the  Remarketing
               Agent has  found  purchasers  (the  "Deficiency  Notice").  At or
               before 3:00 p.m.,  New York City time,  on the Business Day prior

               Agent,  but in any event, no later than 12:00 noon, New York City
               time,  on the Purchase  Date (or two  Business  Days prior to the
               Purchase  Date in the event  tendered  Bonds  accrue  interest at
               Multiannual  or Fixed Rates),  the  Remarketing  Agent shall give
               notice to the  Paying  Agent by  Electronic  Notice of the names,
               addresses and taxpayer  identification numbers of the purchasers,
               the denominations of Bonds to be delivered to each purchaser and,
               if  available,   payment  instructions  for  regularly  scheduled
               interest  payments,  or of any  changes  in any such  information
               previously communicated.

                    (ii) Sources of Payments.  The Remarketing Agent shall cause
               to be paid to the Paying Agent on the  Purchase  Date of tendered
               Bonds,  all amounts  representing  proceeds of the remarketing of
               such Bonds to persons  other than the  Issuer,  the Company or an
               affiliate thereof,  such payments to be made in the manner and at
               the time specified in subsection  2.10 (a) above.  If the amounts
               specified in the Deficiency  Notice will not be sufficient to pay
               the  Purchase  Price on the  Purchase  Date,  the  Company  shall
               deliver or cause to be  delivered  such  amounts at such times so
               that there will be delivered to the Paying Agent (A)  immediately
               available  funds in an amount equal to such  deficiency  prior to
               2:30 p.m.,  New York City time,  on the Purchase Date of tendered
               Bonds accruing  interest at Daily Rates (3:00 p.m., New York City
               time,  in the  case of  Flexible  Rate  Bonds),  (B)  immediately
               available  funds in an amount equal to such  deficiency  prior to
               1:15 p.m.,  New York City time,  on the Purchase Date of tendered
               Bonds  accruing  interest  at  Weekly,   Monthly,   Quarterly  or
               Semiannual Rates, and (C) clearinghouse  funds in an amount equal
               to such  deficiency  prior to 12:15 p.m.,  New York City time, on
               the  Purchase  Date  of  tendered  Bonds  accruing   interest  at
               Multiannual  or Fixed  Rates (the  obligation  of the  Company to
               deliver  such  moneys  not being  conditioned  on  receipt by the
               Company or the Agent of the  foregoing  notice from the Trustee).
               All moneys  received by the Paying Agent as remarketing  proceeds
               and additional amounts, if any, received from the Company, as the
               case  may be,  shall  be  deposited  by the  Paying  Agent in the
               appropriate  account of the Bond  Purchase Fund to be used solely
               for the payment of the Purchase Price of tendered Bonds and shall
               not be  commingled  with other funds held by the Paying Agent and
               shall not be invested.

                    (iii) Payments by the Paying Agent.  At or before 4:30 p.m.,
               New York City time, on the Purchase  Date for tendered  Bonds and
               upon  receipt  by the  Paying  Agent  of  100%  of the  aggregate
               Purchase Price of the tendered Bonds,  the Paying Agent shall pay
               or receipt  the  Purchase  Price of such Bonds to the  Registered
               Owners  thereof.  Such  payments  shall  be made  in  immediately
               available  funds (or by wire  transfer),  unless  the Bonds to be
               purchased accrue interest at Multiannual or Fixed Rates, in which
               event such payments  shall be made in  clearinghouse  funds.  The
               Paying Agent shall make payment of the Purchase Price by applying
               in  order  of  priority  (A)  first,  moneys  paid  to it by  the
               Remarketing Agent as proceeds of the remarketing of such Bonds by
               the  Remarketing  Agent,  and  (B)  second,   other  moneys  made
               available by the Company.

                    (iv)  Registration  and  Delivery of  Tendered or  Purchased
               Bonds.  On the date of purchase,  the Paying Agent shall register
               and  deliver  (or hold) or  cancel  all  Bonds  purchased  on any
               Purchase  Date as follows:  (A) Bonds  purchased or remarketed by
               the  Remarketing  Agent shall be registered and made available to
               the  Remarketing  Agent by 2:15  p.m.,  New York  City  time,  in
               accordance with the  instructions of the Remarketing  Agent,  and
               (B) Bonds purchased with amounts provided by the Company shall be
               registered  in the name of the Company and shall be  delivered to
               the  Trustee to be held in trust by the  Trustee on behalf of the
               Company  and shall not be  released  from such  trust  unless the
               Trustee  shall  have  received  written   instructions  from  the
               Company. Notwithstanding anything herein to the contrary, so long
               as the  Bonds  are held  under  the  book-entry  only  system  in
               accordance with Section 3.07 hereof,  Bonds will not be delivered
               as set forth above; rather,  transfers of beneficial ownership of
               the Bonds to the person  indicated  above will be effected on the
               registration books of DTC pursuant to its rules and procedures.

                    (v) (Intentionally Omitted).

                    (vi) Resale of Bonds Purchased by the Company.  In the event
               that  any  Bonds  are  registered  to  the  Company  pursuant  to
               subparagraph  (iv) above,  to the extent  requested by the Agent,
               the  Remarketing  Agent  shall  offer  for  sale and use its best
               efforts  to sell  such  Bonds at a price  equal to the  principal
               amount thereof plus accrued interest.

                    (vii)  Delivery  of  Tendered  Bonds;  Effect of  Failure to
               Surrender  Bonds.  All Bonds to be purchased on any date shall be
               required to be  delivered to the  principal  office of the Paying
               Agent at or  before  11:00  a.m.,  New  York  City  time,  on the
               Purchase  Date. If the Owner of any Bond (or portion  thereof) in
               certificated  form  that is  subject  to  optional  or  mandatory
               purchase  pursuant to this Article  fails to deliver such Bond to
               the Trustee for purchase on the Purchase  Date, and if the Paying
               Agent is in receipt of the Purchase Price therefor, such Bond (or
               portion  thereof) shall  nevertheless be deemed  purchased on the
               Purchase  Date  thereof  and  ownership  of such Bond (or portion
               thereof)  shall  be  transferred  to  the  purchaser  thereof  as
               provided in subsection (ii) above. Any Owner who fails to deliver
               such Bond for purchase  shall have no further  rights  thereunder
               except the right to  receive  the  Purchase  Price  thereof  upon
               presentation  and surrender of said Bond to the Paying Agent. The
               Paying Agent shall,  as to any tendered Bonds which have not been
               delivered to it (1) promptly notify the Remarketing Agent of such
               nondelivery,  and (2) place or cause to be placed a stop transfer
               against an appropriate  amount of Bonds registered in the name of
               such  Registered  Owner(s) on the bond  registration  books.  The
               Paying  Agent  shall  place or cause to be  placed  such  stop(s)
               commencing  with the lowest serial number Bond  registered in the
               name of such  Registered  Owner(s) until stop transfers have been
               placed  against  an   appropriate   amount  of  Bonds  until  the
               appropriate  tendered  Bonds are  delivered to the Paying  Agent.
               Upon such delivery, the Paying Agent shall make or cause the Bond
               Registrar  to  make  any  necessary   adjustments   to  the  bond
               registration  books.   Notwithstanding  anything  herein  to  the
               contrary, so long as the Bonds are held under the book-entry only
               system in accordance with Section 3.07 hereof,  Bonds will not be
               delivered as set forth  above;  rather,  transfers of  beneficial
               ownership  of the Bonds to the  person  indicated  above  will be
               effected  on the  registration  books of the DTC  pursuant to its
               rules and procedures.

     Section 2.11. Mandatory Tenders for Purchase.

                    (a) Flexible. Each Bond accruing interest at a Flexible Rate
               shall  be  subject  to  mandatory  tender  for  purchase  on each
               Interest  Payment Date  applicable  to such Bond, at the Purchase
               Price  applicable to such Bond. The Registered  Owner of any Bond
               accruing  interest  at a Flexible  Rate shall  provide the Paying
               Agent with written payment instructions for the Purchase Price of
               its Bond on or before tender thereof to the Paying Agent.

                    (b) Conversions  between Interest Rate Periods.  Bonds to be
               converted  from one Mode to a  different  Mode (other than from a
               Daily  Mode to a  Weekly  Mode or from a  Weekly  Mode to a Daily
               Mode) or a change  from one  Interest  Rate Period to an Interest
               Rate Period of different duration within the Multiannual Mode are
               subject to mandatory  tender for purchase on the Conversion  Date
               at the Purchase Price  applicable to such Bonds. The Paying Agent
               shall give notice of such  mandatory  tender for  purchase to the
               Registered  Owners of Bonds by first class mail, not less than 15
               days  before  the  mandatory  tender  date.  If the  Bonds are in
               certificated  form,  such notice shall include  information  with
               respect to required  delivery of Bond certificates and payment of
               the Purchase Price.

                    (c) Mandatory Tender in lieu of Optional Redemption. For any
               Bond in the  Multiannual  or Fixed Rate Mode, the Agent may elect
               to convert from the Multiannual or Fixed Rate Mode to a different
               Mode or change from one Interest  Rate Period to an Interest Rate
               Period of different  duration within the Multiannual  Mode on any
               optional redemption date for such Bond. The Agent shall make such
               election in  accordance  with  Section  2.02 hereof and upon such
               election  such Bond  shall be  subject  to  mandatory  tender for
               purchase on the Conversion Date in lieu of optional redemption at
               the Purchase  Price  applicable  to such Bonds.  The Paying Agent
               shall give notice of such  mandatory  tender for  purchase to the
               Registered  Owners of Bonds by first class mail, not less than 30
               days  before  the  mandatory  tender  date.  If the  Bonds are in
               certificated  form,  such notice shall include  information  with
               respect to required  delivery of Bond certificates and payment of
               the Purchase Price.

     Section 2.12.  Special  Conditions to Conversions from Multiannual or Fixed
Rate Mode.  Notwithstanding  any other provision contained herein, no conversion
from the  Multiannual  or Fixed Rate Mode to a different Mode or change from one
Interest Rate Period to an Interest Rate Period of different duration within the
Multiannual  Mode on any  optional  redemption  date for a Bond shall take place
unless  there is delivered to the Trustee at least 45 days prior to the proposed
Conversion  Date  (a)  written  evidence  that  the  Bonds  will  qualify  for a
short-term  credit  rating from a Rating  Agency and (b) written  consent of the
Bond  Insurer  to the  conversion  of such  Bond,  which  consent  shall  not be
unreasonably withheld.



                                                       
                                   ARTICLE III

                    (c) The Company in issuing the Bonds may use "CUSIP" numbers
               (if then  generally  in use),  and, if so, the Trustee  shall use
               "CUSIP"  numbers in notices of  redemption  as a  convenience  to
               Holders;  provided  that  any  such  notice  may  state  that  no
               representation  is made  as to the  correctness  of such  numbers
               either as printed on the Bonds or as contained in any notice of a
               redemption  and that  reliance  may be  placed  only on the other
               identification  numbers  printed  on  the  Bonds,  and  any  such
               redemption  shall not be affected by any defect in or omission of
               such numbers.

                    (d) Notwithstanding any other provision of this Indenture or
               in the  forms of Bond,  if the  Bonds  are on  deposit  at DTC in
               accordance with Section 3.07 hereof,  presentation  and surrender
               of the Bonds at the Principal  Office of the Trustee shall not be
               required other than at the maturity thereof.

     Section 3.03.  Performance of Covenants;  Issuer  Immunity.  (a) The Issuer

               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 Indenture.  The Issuer's  immunity and protection
               from liability  hereunder  shall survive the final payment of the
               Bonds.

     Section 3.04.  Instruments of Further Assurance.  The Issuer covenants that
it will do,  execute,  acknowledge and deliver,  or cause to be done,  executed,

Estate, except the lien and charge granted hereby.

financing  statements and all supplements thereto, and such other instruments as

such  manner  and in such  places  as from time to time may be  directed  by the
Company.


     Section 3.06.  Registration  of Bonds;  Trustee  Appointed Bond  Registrar;
Persons Treated as Owners.


                    (a)  Registration.  The Trustee is hereby  appointed as Bond
               Registrar   of  the  Bonds  and  as  such  shall   maintain   the
               Registration  Books in the  State of  Texas as  provided  by this
               Indenture.  The Registration  Books shall reflect the information
               required to be provided  by Bond  Owners in  connection  with the
               transfer  of Bonds.  At  reasonable  times  and under  reasonable
               regulations  established by the Trustee,  the Registration  Books
               may be inspected and copied by the Company, the Agent, the Issuer
               or the Owners (or designated representatives thereof) of at least
               25% in aggregate principal amount of Bonds then Outstanding.

                    (b) Transfer and  Exchange.  The  ownership of a Bond may be
               transferred  (in  Authorized  Denominations)  only upon surrender
               thereof at the Principal Office of the Trustee, accompanied by an
               assignment,  duly  executed by the Owner of such Bond or his duly
               authorized   attorney-in-fact,   in  such   form  as   shall   be
               satisfactory  to the  Trustee,  along with the address and social
               security number or federal employer identification number of such
               transferee  (or,  if  registration  is to be made in the  name of
               multiple  individuals,  of all  such  transferees)  and,  if such
               transferee is a trust, the name and address of the trustee(s) and
               the date of the trust of the  proposed  transferee.  Upon the due
               presentation  of any  Bond for  transfer  and on  request  of the
               Trustee,  the Issuer shall execute in the name of the transferee,
               and the  Trustee  shall  authenticate  and  deliver,  a new fully
               registered  Bond or Bonds of the same Mode,  in any  denomination
               permitted by this  Indenture,  in an aggregate  principal  amount
               equal to the unmatured and unredeemed  aggregate principal amount
               of such  transferred  fully registered Bond, and bearing interest
               at the  same  rate,  and  maturing  on the  same  date,  as  such
               transferred Bond.

                    Bonds  may be  exchanged  at  the  Principal  Office  of the
               Trustee or the Paying Agent for other Bonds of the same Mode (and
               same  Interest  Rate Period with respect to Bonds in the Flexible
               Mode or Multiannual  Mode)  aggregating a like principal  amount.
               Bonds  issued in  exchange  for other Bonds may be issued only in
               Authorized  Denominations of the same Mode. All Bonds surrendered
               to the Trustee for  exchange  pursuant to this Section 3.06 shall
               be canceled by the Trustee and shall not be redelivered.  Neither
               the Issuer nor the  Trustee  shall be  required  to make any such
               transfer or  exchange  of any Bond  during the 10  Business  Days
               immediately  preceding the mailing of a notice of Bonds  selected
               for redemption or, with respect to a Bond, after such Bond or any
               portion thereof has been selected for redemption.

                    (c)  Charges.  In all cases of the  transfer of a Bond,  the
               Trustee shall register at the earliest  practicable  time, on the
               Registration  Books,  such Bond in accordance with the provisions
               of this Indenture. The Issuer or the Trustee may make a charge to
               the  Bond  Owner  for  every  transfer  or  exchange  of  a  Bond
               sufficient  to  reimburse  it for any tax or  other  governmental
               charge  required  to be paid with  respect  to such  transfer  or
               exchange,  and may demand that such charge be paid before any new
               Bond is delivered.

                    (d) Ownership.  As to any Bond, the person in whose name the
               ownership of such Bond shall be  registered  on the  Registration
               Books shall be deemed and regarded as the absolute  owner thereof
               for all  purposes,  and payment of or on account of the principal
               of any such Bond and the premium,  if any,  and interest  thereon
               shall be made only to or upon the order of the  registered  Owner
               thereof or his legal  representative.  All such payments shall be
               valid and effectual to satisfy and  discharge the liability  upon
               such Bond,  including the premium,  if any, and interest thereon,
               to the extent of the sum or sums so paid.

     Section 3.07.  Book-Entry Only System.  The Bonds shall be initially issued
in the form of a single  fully  registered  Bond.  Upon  initial  issuance,  the
ownership  of each such Bond shall be  registered  in the name of Cede & Co., as
nominee of DTC,  and,  except as provided  in Section  3.08  hereof,  all of the
outstanding  Bonds shall be  registered in the name of Cede & Co., as nominee of
DTC.
                                                        
     With respect to Bonds  registered  in the name of Cede & Co., as nominee of
DTC, the Issuer and the Trustee  shall have no  responsibility  or obligation to
any DTC  Participant  or to any person on behalf of whom such a DTC  Participant
holds an interest in the Bonds,  except as provided in this  Indenture.  Without
limiting the immediately  preceding  sentence,  the Issuer and the Trustee shall
have no  responsibility  or  obligation  with respect to (i) the accuracy of the
records of DTC, Cede & Co. or any DTC Participant  with respect to any ownership
interest in the Bonds,  (ii) the  delivery to any DTC  Participant  or any other
person,  other than a Bondholder,  as shown on the  Registration  Books,  of any
notice with respect to the Bonds,  including any notice of redemption,  or (iii)
the payment to any DTC Participant or any other person, other than a Bondholder,
as shown in the  Registration  Books of any amount with respect to principal of,
premium, if any, or interest on, the Bonds.  Notwithstanding any other provision
of this Indenture to the contrary,  the Issuer and the Trustee shall be entitled
to treat and  consider the person in whose name each Bond is  registered  in the
Registration Books as the absolute owner of such Bond for the purpose of payment
of principal,  premium,  if any, and interest with respect to such Bond, for the
purpose of giving  notices of redemption  and other matters with respect to such
Bond,  for the purpose of  registering  transfers with respect to such Bond, and
for all other  purposes  whatsoever.  The Trustee  shall pay all  principal  of,
premium,  if any,  and  interest  on the Bonds  only to or upon the order of the
respective  owners,  as shown in the  Registration  Books  as  provided  in this
Indenture,  or their  respective  attorneys duly authorized in writing,  and all
such  payments  shall be valid and  effective to fully satisfy and discharge the
Issuer's  obligations with respect to payment of principal of, premium,  if any,
and interest  on, the Bonds to the extent of the sum or sums so paid.  No person
other than an owner, as shown in the  Registration  Books,  shall receive a Bond
certificate  evidencing  the  obligation  of the  Issuer  to  make  payments  or
principal,  premium,  if any, and  interest,  pursuant to this  Indenture.  Upon
delivery  by DTC to the  Trustee  of written  notice to the effect  that DTC has
determined  to  substitute  a new nominee in place of Cede & Co., and subject to
the provisions in this Indenture with respect to interest checks or drafts being
mailed to the registered  owner at the close of business on the Record Date, the
words "Cede & Co." in this Indenture shall refer to such new nominee of DTC.

     Section 3.08. Successor Securities Depository; Transfers Outside Book-Entry
Only System.  (a) In the event that the Issuer, at the direction of the Company,
determines that DTC is incapable of discharging its  responsibilities  described
herein and in the  representation  letter of the Issuer to DTC, the Issuer shall
(i) appoint a successor  securities  depository,  qualified to act as such under
Section 17(a) of the Securities Exchange Act of 1934, as amended, notify DTC and
DTC  Participants,  identified  by DTC,  of the  appointment  of such  successor
securities  depository and transfer one or more separate Bonds to such successor
securities  depository  or (ii) notify DTC and DTC  Participants,  identified by
DTC, of the availability  through DTC of Bonds and transfer one or more separate
Bonds to DTC Participants, identified by DTC, having Bonds credited to their DTC
accounts.  In such  event,  the Bonds  shall no longer  be  restricted  to being
registered  in the  Registration  Books in the name of Cede & Co., as nominee of
DTC, but may be registered in the name of the successor  securities  depository,
or its  nominee,  or in  whatever  name or  names  Bondholders  transferring  or
exchanging  Bonds shall  designate,  in accordance  with the  provisions of this
Indenture.

                    (b) In  addition to (a) above,  upon the written  consent of
               100% of the  beneficial  owners of the Bonds,  the Trustee  shall
               withdraw the Bonds from DTC, and  authenticate  and deliver Bonds
               fully  registered to the assignees of DTC or its nominee.  If the
               request  for such  withdrawal  is not the  result  of any  Issuer
               action or inaction, such withdrawal,  authentication and delivery
               shall be at the cost and expense  (including  costs of  printing,
               preparing and  delivering  such Bonds) of the persons  requesting
               such withdrawal, authentication and delivery.

     Section 3.09. Payments to Cede & Co. Notwithstanding any other provision of
this Indenture to the contrary, so long as any Bond is registered in the name of
Cede & Co.,  as nominee of DTC,  all  payments  with  respect to  principal  of,
premium, if any, and interest on, such Bond and all notices with respect to such
Bond  shall be made and  given,  respectively,  in the  manner  provided  in the
representation letter of the Issuer to DTC.

     Section 3.10.  Cancellation.  All Bonds which have been paid at maturity or
redeemed  prior to maturity  shall not be reissued  but shall be canceled by the
Trustee. All Bonds which are canceled by the Trustee shall be disposed of by the
Trustee, in accordance with its document retention  policies,  and a certificate
of  cancellation  shall  be  furnished  promptly  to the  Issuer  upon  request;
provided,  however,  that if the Issuer shall so direct the Trustee, the Trustee
shall forward the canceled Bonds to the Issuer.

                                                        
     Section 3.11.  Non-presentment of Bonds. If any check or draft representing
payment of interest, principal or premium on any Bond is returned to the Trustee
or is not  presented  for  payment  by the  payee  thereof,  or any  Bond is not
presented  for payment of  principal  or premium at the  maturity or  redemption
date, if moneys and/or Government  Obligations  sufficient to pay such interest,
or such principal and premium, shall have been deposited with and made available
to the  Trustee  for the  benefit  of the  Owner  of the  applicable  Bond,  all
liability  of the  Issuer to the Owner of such  Bond for such  interest  or such
principal  and  premium  shall  forthwith  cease,  terminate  and be  completely
discharged,  and  thereupon  it shall be the duty of the  Trustee  to hold  such
moneys and/or Government Obligations,  without investing or reinvesting the same
and without liability for interest thereon, for the benefit of the Owner of such
Bond, who shall thereafter be restricted exclusively to such funds for any claim
of whatever  nature on such  Owner's  part under this  Indenture  or on, or with
respect  to,  such  Bond,  and such Bond  shall no longer  be  considered  to be
Outstanding.  The Trustee's  obligation  to hold such moneys  and/or  Government
Obligations relating to the Bonds shall continue for a period equal to two years
following the date on which the  principal of all Bonds has become due,  whether
at  maturity,  or at the date  fixed for  redemption  or  purchase  thereof,  or
otherwise,  at which time the Trustee, upon payment of all fees and expenses due
and owing to it and receipt of indemnity satisfactory to it, shall surrender any
remaining  funds so held to the Company.  Following  such  surrender,  any claim
under this  Indenture by the Owner of any Bond of whatever  nature shall be made
only upon the Company.

     The  provisions  of this  Section  3.11 shall be subject to all  applicable
escheat laws, including Title 6 of the Texas Property Code.

     Section 3.12. Rights under Agreement. This Indenture, the Agreement and the
documents  executed  by the  Company  in  connection  therewith,  duly  executed
counterparts  or originals of which have been filed with the Trustee,  set forth
the covenants and the  obligations  of the Issuer,  the Company and the Trustee.
Reference  hereby  is made to such  documents  for  detailed  statements  of the
covenants and  obligations  set forth therein.  The Issuer and the Trustee agree
that the Trustee,  for and on behalf of the Bond Owners,  in its name or, to the
extent  permitted  by law, in the name of the Issuer,  may enforce all rights of
the Issuer  (except for  Unassigned  Rights) and all  obligations of the Company
under and pursuant to the Agreement and such documents.

     Section 3.13. Legal Existence of Issuer.  The Issuer covenants that it will
take any action within its control to maintain its legal existence and will duly
procure any necessary renewals and extensions thereof; will use its best efforts
to  maintain,  preserve  and  renew  all  the  rights,  powers,  privileges  and
franchises owned by it; and will comply with all valid acts, rules,  regulations
and  orders of any  legislative,  executive,  judicial  or  administrative  body
applicable to the Issuer in connection with the Bonds.

     Section 3.14.  Diminution of, or Encumbrance  on, Trust Estate.  The Issuer
covenants not to sell, transfer,  assign, pledge, release, encumber or otherwise
diminish or dispose of, directly or indirectly, by merger or otherwise, or cause
or suffer  the same to occur,  or create or allow to be  created or to exist any
lien  upon,  all or any part of its  interests  in the Trust  Estate,  except as
expressly permitted by this Indenture.

     Section 3.15.  Books,  Records and Accounts.  The Trustee shall keep proper
books for the  registration  of, and  transfer of ownership  of, each Bond,  and
proper books,  records and accounts in which complete and correct  entries shall
be made of all transactions relating to the receipt,  disbursement,  investment,
allocation and application of the proceeds  received from the sale of the Bonds,
the revenues received from the Agreement,  the documents executed by the Company
in  connection  therewith,  the  funds and  accounts  created  pursuant  to this
Indenture,  and all other  moneys  held by the  Trustee  hereunder.  The Trustee
shall, during regular business hours and upon reasonable prior notice, make such
books,  records and  accounts  available  for  inspection  by the Issuer and the
Company.

     Section  3.16.  Temporary  Bonds.  Until  definitive  Bonds  are  ready for
delivery,  there may be executed,  and, upon written request of the Issuer,  the
Trustee shall authenticate and deliver, in lieu of definitive Bonds, but subject
to  the  same   limitations  and  conditions,   temporary   printed,   engraved,
lithographed or typewritten  registered Bonds (without coupons),  in the minimum
denomination  permitted for definitive Bonds or any integral  multiple  thereof,
substantially of the tenor  hereinabove set forth for definitive Bonds, and with
such omissions,  insertions and variations as may be  appropriate.  If temporary
Bonds  shall be  issued,  the  Issuer  shall  cause the  definitive  Bonds to be
prepared and to be executed and deposited with the Trustee, without undue delay,
and  the  Trustee,  upon  presentation  to it at  its  Principal  Office  of any
temporary Bond,  shall cancel the same and  authenticate and deliver in exchange
therefor  at the  required  location,  without  charge to the Owner  thereof,  a
definitive  Bond or Bonds of an equal  aggregate  principal  amount and  bearing
interest at the same rate as the temporary Bond or Bonds so  surrendered.  Until
so exchanged the  temporary  Bonds shall be entitled in all respects to the same
benefit and security of this Indenture as the definitive  Bonds to be issued and
authenticated hereunder.

     Section 3.17.  Mutilated,  Lost,  Stolen or Destroyed Bonds. If any Bond is
mutilated,   lost,  stolen  or  destroyed,  the  Trustee,  upon  request,  shall
authenticate  a new Bond,  dated as provided  in Article II hereof,  of the same
denomination  and  Mode  and  bearing  interest  at the  same  rate as the  Bond
mutilated,  lost, stolen or destroyed;  provided,  however, that, in the case of
any  mutilated  Bond,  such  mutilated  Bond shall first be  surrendered  to the
Trustee,  and, in the case of any lost,  stolen or destroyed  Bond,  there shall
first be furnished to the Trustee  evidence of such loss,  theft or  destruction
satisfactory to the Trustee,  together with indemnity covering the Trustee,  the
Company and the Issuer  satisfactory to the Trustee. If any such Bond shall have
matured  instead of issuing a duplicate  Bond the Trustee may pay the same.  The
Trustee  and the Issuer may charge the Owner of such Bond with their  reasonable
fees and expenses in connection with the issuance of any such duplicate Bond.

     Section 3.18. Intentionally Omitted.

     Section 3.19. Arbitrage Covenants. The Issuer covenants and agrees, for the
benefit of the owners of the Bonds,  that it will not knowingly  take any action
or omit from taking nor  instruct the Trustee to take or to omit from taking any
action,  which  would  result in a loss of the  exemption  from  federal  income
taxation  of  interest  on the Bonds by virtue  of the  Bonds  being  considered
"arbitrage bonds" within the meaning of section 148 of the Code.


                                                       
                                   ARTICLE IV

                       USE OF PROCEEDS; REVENUES AND FUNDS

     Section 4.01.  Application of Original  Proceeds of Bonds. (a) The proceeds
of the sale of the Bonds, except accrued interest thereon, if any, shall, on the
Issue Date, be  transferred by the Trustee to the Prior Trustee for deposit into
the bond fund created under the Prior Indenture.

                    (b) The Company, prior to or on the Issue Date, will deposit
               or cause to be deposited into the bond fund relating to the Prior
               Bonds an amount which,  together with the Bond proceeds described
               in (a) above,  will equal the principal of,  premium and interest
               on the Prior Bonds due on the date fixed for their redemption.

     Section 4.02.  Creation of Bond Fund. There is hereby created by the Issuer
and ordered  established with the Trustee a trust fund to be designated the "Red
River Authority of Texas Pollution  Control Revenue  Refunding Bonds (West Texas
Utilities  Company,  Public  Service  Company of Oklahoma and Central  Power and
Light Company Oklaunion Project) Series 1996 Bond Fund" (the "Bond Fund").

     Section 4.03.  Payments into Bond Fund and Use of Moneys in Bond Fund.  (a)
There  shall be  deposited  into the  Bond  Fund,  when  received:  (i)  accrued
interest,  if any, on the Bonds from the date thereof to the date of delivery to
the initial  purchaser  thereof;  (ii) all payments  specified in the  Agreement
(except for certain payments of fees, expenses, and indemnification  arising out
of the Issuer's Unassigned Rights); (iii) all moneys required to be so deposited
in  connection  with any  redemption of Bonds;  (iv) any amounts  directed to be
transferred into the Bond Fund pursuant to any provision of this Indenture;  and
(v) all other  moneys  when  received by the  Trustee  which are  required to be
deposited into the Bond Fund or which are  accompanied  by directions  that such
moneys are to be paid into the Bond Fund.

                    (b) Moneys  held in the Bond Fund  shall be used  solely for
               the payment of the principal of, premium, if any, and interest on
               the Bonds on the dates due for the payment or redemption thereof.
               The Issuer hereby  authorizes and directs the Trustee to withdraw
               sufficient  funds  from the Bond  Fund to pay the  principal  of,
               premium, if any, and interest on the Bonds as the same become due
               and payable, which authorization and direction the Trustee hereby
               accepts.

     Section  4.04.  Creation  and Use of Bond  Purchase  Fund.  There is hereby
created and  established  a Bond  Purchase  Fund with respect to the Bonds to be
held as a separate escrow fund, in trust and administered and distributed by the
Trustee as provided in this Section.  All moneys  deposited in the Bond Purchase
Fund shall be used solely for the purposes set forth herein.

     The Trustee shall  deposit into the Bond Purchase Fund (i) all  Remarketing
Proceeds received by the Trustee from the Remarketing Agent; and (ii) funds paid
by the Company  pursuant to Section  5.10 of the  Agreement.  The Trustee  shall
apply moneys on deposit in the Bond Purchase  Fund to pay the Purchase  Price of
Bonds purchased hereunder;  provided,  however, that any amounts received by the
Trustee from the Remarketing Agent that are not needed to pay the Purchase Price
of Bonds because such Bonds have been accelerated or called for redemption shall
be returned to the Remarketing Agent.

     The funds  held by the  Paying  Agent in the Bond  Purchase  Fund shall not
constitute  part of the  Trust  Estate  which  is  subject  to the  lien of this
Indenture.  The moneys in the Bond Purchase Fund shall be used solely to pay the
Purchase Price of Bonds as aforesaid and may not be used for any other purposes.
It shall be the duty of the Paying Agent to hold the moneys in the Bond Purchase
Fund, without liability for interest thereon,  for the benefit of the Registered
Owners of Bonds  which  have  been  properly  tendered  for  purchase  or deemed
tendered on the Purchase Date, and if sufficient funds to pay the Purchase Price
for such  tendered  Bonds shall be held by the Paying Agent in the Bond Purchase
Fund for the benefit of the  Registered  Owners  thereof,  each such  Registered
Owner shall  thereafter be restricted  exclusively to the Bond Purchase Fund for
any  claim of  whatever  nature  on such  Registered  Owner's  part  under  this
Indenture or on, or with respect to, such tendered Bond.  Funds held in the Bond
Purchase Fund for the benefit of Registered  Owners of untendered Bonds shall be
held in trust and not invested.

     The  provisions  of Section  3.11 hereof shall govern any funds held in the
Bond  Purchase  Fund  for such  Registered  Owners  of the  Bonds  which  remain
unclaimed for a period of two years after the applicable Purchase Date.

     Section 4.05. Investment of Moneys. Subject to the restrictions hereinafter
set forth in this Section 4.05 and in Section 4.08,  any moneys held in the Bond
Fund  shall  be  invested  and  reinvested  by  the  Trustee  upon  the  written
instructions  of the Agent  solely in Permitted  Investments,  maturing no later
than the date on which it is  estimated  by the Agent that such  moneys  will be
required to be paid out hereunder.  All investment  instructions hereunder shall
be provided to the Trustee no later than one Business Day prior to the making of
the  investment  directed  therein.  The  Trustee  may  make  any and  all  such
investments  through its own investment  department and may trade with itself in
the purchase and sale of securities for such investment when authorized to do so
by the Agent.  The Trustee  shall be entitled to rely on all written  investment
instructions  provided  by  the  Agent  hereunder.  The  Trustee  shall  not  be
responsible or liable for the performance of any such investments or for keeping
the moneys held by it  hereunder  fully  invested  at all times.  Any moneys for
which the Trustee has received no investment instructions shall be automatically
reinvested into The Bank of New York Deposit Reserve or a permitted money market
fund as may be authorized by the Agent. Any obligations  acquired by the Trustee
as a result of such  investment  or  reinvestment  shall be held by or under the
control of the Trustee (except for such investments held in book entry form) and
shall be deemed to  constitute a part of the Fund from which the moneys used for
its purchase were taken. All investment  income shall be retained in the Fund to
which the investment is credited from which such income is derived. Although the
Company recognizes that it may obtain a broker confirmation or written statement
containing  comparable  information  at no additional  cost,  the Company hereby
agrees that  confirmations  of investments  made by the Trustee pursuant to this
Section  4.05 are not  required  to be issued by the  Trustee  for each month in
which a monthly  statement  is  rendered.  No such  statement  need be  rendered
pursuant to the provisions hereof if no activity occurred in the fund or account
during  such  preceding  month.  All funds held under  this  Indenture  shall be
secured to the fullest  extent  required by Texas law. In the event of a loss on
the sale of such  investments  (after  giving  effect to any  interest  or other
income  thereon  except to the  extent  theretofore  paid to the  Company),  the
Trustee  shall have no  responsibility  in respect of such loss  except that the
Trustee  shall notify the Agent of the amount of such loss and the Company shall
promptly  pay such  amount to the  Trustee to be  credited as part of the moneys
originally invested. If the amount on deposit in any fund is insufficient on any
Interest  Payment Date,  redemption date or Purchase Date to make timely payment
due on such date,  the Company shall deposit  sufficient  moneys in such fund to
enable timely payment to be made on such date.

     Section  4.06.  Moneys  To Be Held in  Trust.  All  moneys  required  to be
deposited  with or paid to the  Trustee  for the  account  of any Fund under any
provisions of this Indenture shall be held by the Trustee in trust,  and, except
for (i) moneys in the Bond  Purchase  Fund and the Rebate Fund,  and (ii) moneys
deposited with or paid to the Trustee for the redemption of Bonds, notice of the
redemption  for which has been duly  given,  shall,  while held by the  Trustee,
constitute  part of the Trust  Estate and be subject  to the  security  interest
created hereby.

     Section 4.07. Repayment to Company from Indenture Funds. Subject to Section
3.11 hereof,  any amounts  remaining in any Fund created  under this  Indenture,
after  payment in full of the Bonds in  accordance  with  Article V hereof,  the
reasonable  fees,  charges  and  expenses  of the  Issuer,  the  Trustee and any
co-trustee  appointed  hereunder,  and all  other  amounts  required  to be paid
hereunder or under the Agreement, shall be paid, upon the expiration of, or upon
the sooner  termination  of, the terms of this  Indenture,  to the Agent,  to be
distributed among WTU, PSO and CPL according to their Ownership Percentages.

     Section 4.08. Custody of Funds and Accounts.  All Funds created pursuant to
this Indenture  shall be in the custody of the Trustee but held in trust, in the
name of the Issuer,  for the benefit of the Bondholders (other than amounts held
in the Bond Purchase Fund).

     Section 4.09.  Exemption from Federal Income Taxation.  The Issuer will not
knowingly take any action, or omit to take any action within its control,  which
action or omission will  adversely  affect the  exclusion  from gross income for
federal  income tax purposes of interest on the Bonds,  and in the event of such
action or omission will promptly,  upon receiving  knowledge  thereof,  take all
lawful actions, based on advice of counsel and at the expense of the Company, as
may rescind or otherwise negate such action or omission.


     Section 4.10. Covenants Regarding Rebate.

                    (a) A  special  Rebate  Fund is  hereby  established  by the
               Issuer.  The  Rebate  Fund  shall be for the sole  benefit of the
               United States of America and shall not be subject to the claim of
               any other person,  including without  limitation the Bondholders.
               The Rebate Fund is established  for the purpose of complying with
               section 148 of the Code and the Treasury Regulations  promulgated
               pursuant  thereto.  The  money  deposited  in  the  Rebate  Fund,
               together  with all  investments  thereof  and  investment  income
               therefrom,  shall be held in trust and applied solely as provided
               in this  Section.  The Rebate  Fund is not a portion of the Trust
               Estate  and is  not  subject  to  the  lien  of  this  Indenture.
               Notwithstanding  the  foregoing,  the Trustee with respect to the
               Rebate  Fund  is  afforded  all  the  rights,   protections   and
               immunities otherwise accorded to it hereunder.

                    (b)   Within   ten  days  after  the  close  of  each  fifth
               anniversary  date of the issuance of the Bonds, the Trustee shall
               receive from the Agent a computation in the form of a certificate
               of an  authorized  officer  of the Agent of the amount of "Excess
               Earnings,"  if  any,  for the  period  beginning  on the  date of
               delivery of the Bonds and ending at the close of such "Bond Year"
               and the Company  shall pay to the  Trustee  for deposit  into the
               Rebate Fund an amount equal to the  difference,  if any,  between
               the amount  then in the Rebate  Fund and the Excess  Earnings  so
               computed.  The term "Bond Year"  means with  respect to the Bonds
               each  one-year  period ending on the  anniversary  of the date of
               delivery  of the Bonds or such other  period as may be elected by
               the Issuer in accordance with the Regulations and notice of which
               election has been given to the  Trustee.  If, at the close of any
               Bond Year,  the amount in the Rebate Fund exceeds the amount that
               would be  required  to be paid to the  United  States of  America
               under  paragraph  (d)  below if the  Bonds had been paid in full,
               such excess may be  transferred  from the Rebate Fund and paid to
               the Company at the written  instructions of the Company,  and the
               Company shall use such excess for such purposes for which,  or to
               be  redeposited  to such  fund  from  which,  such  amounts  were
               originally derived.

                    (c) In  general,  "Excess  Earnings"  for any period of time
               means the sum of

                    (i) the excess of --

                    (A) the  aggregate  amount earned during such period of time
               on  all  "Nonpurpose   Investments"   (including   gains  on  the
               disposition of such Obligations) in which "Gross Proceeds" of the
               issue are invested (other than amounts  attributable to an excess
               described in this subparagraph (c)(i), over

                    (B) the  amount  that  would have been  earned  during  such
               period  of time if the  "Yield"  on such  Nonpurpose  Investments
               (other than amounts  attributable to an excess  described in this
               subparagraph  (c)(i))  had been  equal to the yield on the issue,
               plus

                    (ii) any income during such period of time  attributable  to
               the excess described in subparagraph (c)(i) above.

     The term Nonpurpose  Investments,  Gross Proceeds, and Yield shall have the
meanings  given to such  terms in  section  148 of the Code and the  Regulations
promulgated pursuant to such section.

                    (d) The Trustee shall pay to the United States of America at
               least  once  every  five  years,  to the  extent  that  funds are
               available  in  the  Rebate  Fund  or  otherwise  provided  by the
               Company,  an amount that  ensures that at least 90 percent of the
               Excess  Earnings  from the date of  delivery  of the Bonds to the
               close of the period for which the payment is being made will have
               been paid.  The Trustee shall pay to the United States of America
               not later than 60 days after the Bonds have been paid in full, to
               the  extent  that  funds  are  available  in the  Rebate  Fund or
               otherwise provided by the Company, 100 percent of the amount then
               required to be paid under section  148(f) of the Code as a result
               of Excess Earnings.

                    (e) The amounts to be computed, paid, deposited or disbursed
               under this  Section  shall be  determined  by the Agent acting on
               behalf of the Issuer within ten days after each fifth anniversary
               of the issuance of the Bonds.  By such date, the Agent shall also
               notify,   in   writing,   the  Trustee  and  the  Issuer  of  the
               determinations  the  Agent  has made and the  payment  to be made
               pursuant to the provisions of this section.  Upon written request
               of any registered owner of Bonds, the Agent shall furnish to such
               registered owner of Bonds a certificate  (supported by reasonable
               documentation,  which may include  calculation by Bond Counsel or
               by some other service  organization) showing compliance with this
               Section  and other  applicable  provisions  of section 148 of the
               Code.

                    (f) The  Trustee  shall  maintain  a record of the  periodic
               determinations  by the Agent of the Excess  Earnings for a period
               beginning  on the first  anniversary  date of the issuance of the
               Bonds and ending on the date six years after the final retirement
               of the Bonds. Such records shall state each such anniversary date
               and  summarize the manner in which the Excess  Earnings,  if any,
               was determined.

                    (g) If the Trustee  shall declare the principal of the Bonds
               and the interest  accrued thereon  immediately due and payable as
               the result of an Event of Default specified in the Indenture,  or
               if the Bonds are  optionally or  mandatorily  prepaid or redeemed
               prior to maturity as a whole in accordance with their terms,  any
               amount  remaining in any of the funds shall be transferred to the
               Rebate  Fund at the  written  instructions  of the Agent,  to the
               extent that the amount  therein is less than the Excess  Earnings
               computed  by the  Agent  as of the date of such  acceleration  or
               redemption,  and  the  balance  of  such  amount  shall  be  used
               immediately  by the Trustee  for the purpose of paying  principal
               of,  redemption  premium,  if any, and interest on the Bonds when
               due.  In  furtherance  of  such  intention,   the  Issuer  hereby
               authorizes  and directs its  President to execute any  documents,
               certificates  or  reports  required  by the Code and to make such
               elections, on behalf of the Issuer, which may be permitted by the
               Code as are  consistent  with the purpose for the issuance of the
               Bonds.

                    (h) The  requirements  contained in this Section relating to
               the  computation  and  payment  of Excess  Earnings  shall not be
               applicable if all Gross Proceeds of the Bonds are expended within
               180 days of the Issue Date.



                                                       
                                    ARTICLE V

                             DISCHARGE OF INDENTURE

     Section  5.01.  Discharge.  If the Issuer shall pay or cause to be paid, or
there shall be otherwise  paid, or provision  shall be made to or for the Owners
of all Bonds for the payment of, the  principal,  premium,  if any, and interest

therein,  and if the Issuer shall not then be in default  under any of the other
covenants  and promises in such Bonds and this  Indenture to be kept,  performed
and  observed by it or on its part,  and if the Issuer  shall pay or cause to be
paid to the  Trustee  all sums of money due or to become  due  according  to the
provisions  hereof or of the Bonds and of the  Agreement,  then,  except for the
rights,  protections  and  immunities  of the Trustee  under Article VII hereof,
these  presents and the interest in the Trust Estate and rights  hereby  granted
shall cease,  determine and be void,  and the Trustee shall take such actions as
may be necessary to evidence the  cancellation and discharge of the lien of this
Indenture. Any Bond, other than a Bond in the Daily or the Weekly Mode, shall be
deemed to be paid within the meaning of this  Article V and for all  purposes of
this Indenture when (i) payment of the principal of, and applicable  premium, if
any, on such Bond plus the  interest  thereon to the due date  thereof  (whether
such due date be by reason of  maturity or upon  redemption  as provided in this
Indenture or  otherwise),  or, in the case of a Bond in the Flexible  Mode,  the
Monthly Mode, the Quarterly Mode, the Semiannual  Mode or the Multiannual  Mode,
to the date next  following  on which such Bond is required to be, or may at the
option of the Owner be,  tendered for purchase,  shall have been provided to the
Trustee by irrevocably  depositing with the Trustee,  in trust,  and the Trustee
shall have irrevocably set aside  exclusively for such payment,  any combination
of (1) moneys provided by the Company sufficient to make such payment and/or (2)
Government Obligations acquired with moneys provided by the Company, not subject
to redemption  or  prepayment  and maturing as to principal and interest in such
amounts and at such times as will,  in the opinion of an  independent  certified
public accountant  delivered to the Trustee,  provide  sufficient moneys to make
such payment without reinvestment (and there shall be no reinvestment); (ii) all
necessary and proper fees,  compensation and expenses of the Trustee  pertaining
to the Bonds shall have been paid or the  payment  thereof  provided  for to the
satisfaction  of the  Trustee;  (iii) the  Trustee  shall have  received in form
satisfactory   to  it  irrevocable   instructions   from  an  Authorized   Agent
Representative  to redeem  such Bonds on the date next  following  on which such
Bond is  required  to be, or may at the  option of the  Owner be,  tendered  for
purchase  and either  evidence  that all  redemption  notices  required  by this
Indenture  have been given or  irrevocable  instructions  to the Trustee to give
such redemption notices has been given; and (iv) there shall be delivered to the
Trustee and the Issuer an opinion of Bond Counsel to the effect that the deposit
of such moneys will not adversely affect the excludability from gross income for
purposes of federal income taxation of interest on any of the Bonds.

     Notwithstanding  the  foregoing,  upon the deposit of funds as described in
the first  paragraph of this Section,  the Purchase  Price of Bonds tendered for
optional or mandatory  purchase shall be made from the remarketing of such Bonds
under Section 2.10 hereof.  If payment of such  Purchase  Price is not made from
such  source,  payment  shall be made from  funds on  deposit  pursuant  to this
Section,  in which case such  Bonds  shall be  surrendered  to the  Trustee  and
canceled.

Obligations,  (ii) the Bond Insurer and the Trustee  shall have received (a) any
final official  statement that may be delivered in connection with any refunding
obligations,  (b) a copy of the accountants'  verification report, (c) a copy of

Bond  Insurer,  and (d) a copy of an opinion of bond  counsel,  addressed to the
Bond  Insurer  and the  Trustee,  to the  effect  that such Bonds have been paid
within the meaning and with the effect expressed in this Indenture, and that the
covenants, agreements and other obligations of the Issuer to the holders of such
Bonds  have been  discharged  and  satisfied  and (iii) the  Trustee  shall have

consent shall not be unreasonably withheld.

                                                        
                                   ARTICLE VI

                         EVENTS OF DEFAULT AND REMEDIES

     Section 6.01.  Events of Default.  Each of the  following  events is hereby
defined  as,  and  declared  to  constitute  an "Event of  Default"  under  this
Indenture:

                    (i) default in the due and punctual payment of the principal
               of or premium, if any, on any Outstanding Bond, as the same shall
               become due and payable,  whether at the stated maturity  thereof,
               upon any proceedings for redemption, or upon the maturity thereof
               by declaration of acceleration;

                    (ii) default in the due and punctual payment of the interest
               on any  Outstanding  Bond,  as the  same  shall  become  due  and
               payable,  and (i) if such  Bond  bears  interest  at a  Flexible,
               Daily,  Weekly,  Monthly,   Quarterly  or  Semiannual  Rate,  the
               continuation  of such default for a period of one Business Day or
               more or (ii) if such Bond  bears  interest  at a  Multiannual  or
               Fixed  Rate,  the  continuation  of such  failure for a period of
               sixty days or more;

                    (iii)  default  in  the  due  and  punctual  payment  of the
               Purchase Price of any Outstanding  Bond, as the same shall become
               due and payable and the continuation of such default for a period
               of one Business Day or more;

                    (iv) default by the Issuer in its  performance or observance
               of any of the other covenants, agreements or conditions contained
               in the Indenture, and the continuation thereof without corrective
               action for the period  after  notice  specified  in Section  6.12
               hereof ; or

                    (v) an Event of Default  (as defined in the  Agreement)  has
               occurred and is continuing under the Agreement.

     Section  6.02.  Acceleration.  If  any  Event  of  Default  occurs  and  is
continuing,  the Trustee  may, and upon request of the owners of at least 25% in
principal amount of all Bonds then  Outstanding,  shall, by notice in writing to
the Issuer and the Agent, declare the principal of all Bonds then Outstanding to
be immediately  due and payable;  and upon such  declaration the said principal,
together with interest accrued thereon to the date of acceleration, shall become
due and payable  immediately at the place of payment provided therein,  anything
in the  Indenture  or in the  Bonds to the  contrary  notwithstanding.  Upon the
occurrence of any acceleration hereunder,  the Trustee shall immediately declare
all payments under the Agreement  pursuant to Section 5.04 thereof to be due and
payable immediately.

     Immediately after any acceleration hereunder, the Trustee, to the extent it
has not already  done so,  shall  notify in writing the Issuer,  the Agent,  the
Paying Agent and the Remarketing  Agent of the occurrence of such  acceleration.
Upon the occurrence of any acceleration  hereunder,  the Trustee shall notify by
first class mail,  postage prepaid,  the owners of all Bonds  Outstanding of the
occurrence of such acceleration.

     If,  after the  principal  of the Bonds has  become  due and  payable,  all
arrears of interest  upon the Bonds are paid by the Issuer,  and the Issuer also
performs  all other  things  in  respect  to which it may have  been in  default
hereunder and pays the  reasonable  charges of the Trustee and the  Bondholders,
including  reasonable  and necessary  attorneys'  fees,  then, and in every such
case,  the  owners  of  a  majority  in  principal  amount  of  the  Bonds  then
Outstanding,  by  notice  to the  Issuer  and to the  Trustee,  may  annul  such
acceleration and its consequences,  and such annulment shall be binding upon the
Trustee and upon all owners of Bonds issued  hereunder.  No such annulment shall
extend  to or  affect  any  subsequent  default  or  impair  any right or remedy
consequent  thereon.  The  Trustee  shall  forward  a copy  of any  notice  from
Bondholders received by it pursuant to this paragraph to the Agent.  Immediately
upon such  annulment,  the Trustee  shall  cancel,  by notice to the Agent,  any
demand for prepayment of all amounts due under the Agreement made by the Trustee
pursuant to this Section. The Trustee shall promptly give written notice of such
annulment to the Issuer,  the Agent,  the Paying Agent,  the Remarketing  Agent,
and,  if notice of the  acceleration  of the Bonds  shall have been given to the
Bondholders, shall give notice thereof to the Bondholders.

                                                        
     Section 6.03. Other Remedies; Rights of Bond Owners. Upon the occurrence of
any Event of Default, the Trustee may pursue any available remedy by suit at law
or in equity to enforce the payment of the  principal of,  premium,  if any, and
interest on the Bonds then outstanding, and the performance by the Issuer of its
obligations hereunder, including, without limitation, the following:

                    (i) by mandamus,  or other suit, action or proceeding at law
               or in equity,  enforce all rights of the  Bondholders and require
               the Issuer to carry out its obligations  under this Indenture and
               the Acts;

                    (ii) bring suit upon the Bonds;

                    (iii) by  action,  suit or  proceeding  at law or in equity,
               require  the Issuer to  account  as if it were the  trustee of an
               express trust for the Bondholders; and

                    (iv) by  action,  suit or  proceeding  at law or in  equity,
               enjoin any acts or things  which may be unlawful or in  violation
               of the rights of the Bondholders.

     Any judgment against the Issuer shall be enforceable only against the Trust
Estate. There shall not be authorized any deficiency judgment against any assets
of, or the  general  credit of, the Issuer.  Subject to the prior  rights of the
Bond  Owners,  the Issuer  shall be  entitled  to  reimbursement  for any of its
expenses in connection  with such  proceeding  from any  available  funds in the
Trust Estate.

     If any Event of Default shall have  occurred,  and if requested to do so in
writing by the Owners of not less than 25% in aggregate  principal amount of the
Bonds then Outstanding and if indemnified as provided in Section 7.01(l) hereof,
the Trustee  shall be obligated to exercise one or more of the rights and powers
conferred by this Section 6.03, or by Section 6.02 hereof as the Trustee,  being
advised by  counsel,  shall deem most  expedient  in the  interests  of the Bond
Owners, unless the Trustee shall determine,  upon the advice of counsel, that to
take such action will prejudice the rights of the majority of the Bond Owners.

     No remedy  conferred  upon or reserved to the Trustee or the Bond Owners by
the terms of this Indenture is intended to be exclusive of any other remedy, but
each and every such  remedy  shall be  cumulative  and in  addition to any other
remedy  given to the Trustee or the Bond Owners  hereunder  or now or  hereafter
existing at law or in equity.  No delay or  omission  to  exercise  any right or
power  accruing upon any default or Event of Default shall impair any such right
or power,  or shall be  construed to be a waiver of any such default or Event of
Default  or an  acquiescence  therein;  and  every  such  right and power may be
exercised  from time to time as often as may be deemed  expedient.  No waiver of
any  default or Event of Default  hereunder,  whether by the Trustee or the Bond
Owners, shall extend to or affect any subsequent default or Event of Default, or
impair any right or remedy consequent thereon.

     Section 6.04. Right of Bond Owners to Direct Proceedings.  Anything in this
Indenture to the contrary  notwithstanding,  upon the  occurrence of an Event of
Default,  the Owners of a majority in  aggregate  principal  amount of the Bonds
then  Outstanding  shall  have the  right,  at any  time,  by an  instrument  or
instruments  in writing  executed and  delivered  to the Trustee,  to direct the
method and place of conducting all  proceedings  to be taken in connection  with
the  enforcement  of the  terms and  conditions  of this  Indenture,  or for the
appointment of a receiver or for any other proceedings hereunder, other than for
the payment of the principal of,  premium,  if any, and interest on the Bonds or
any part thereof; provided,  however, that direction shall not be otherwise than
in  accordance  with the  provisions  of law and  this  Indenture  and  shall be
accompanied by an indemnity as provided in Section 7.01(1) hereof.

     Section 6.05.  Appointment of Receiver.  Upon the occurrence of an Event of
Default,  and  upon  the  filing  of a suit or other  commencement  of  judicial
proceedings  to enforce the rights of the Trustee and the Bond Owners under this
Indenture,  the Trustee shall be entitled,  as a matter of right, to request the
appointment  of a receiver or receivers  of the Trust  Estate and the  revenues,
issues,   earnings,   income,   products  and  profits  thereof,   pending  such
proceedings, with such powers as the court making such appointment shall confer.



     Section 6.06.  Waiver of Certain Laws.  Upon the  occurrence of an Event of
Default, to the extent that such rights may then lawfully be waived, neither the
Issuer,  nor anyone  claiming  through or under it,  shall claim or seek to take
advantage of any appraisement, valuation, stay, extension or redemption laws now
or  hereafter  in force in order to prevent or hinder  the  enforcement  of this
Indenture.  The  Issuer,  for itself and all who may claim  through or under it,
hereby waives, to the extent that it lawfully may do so, the benefit of all such
laws.

     Section  6.07.  Application  of Moneys.  All moneys  relating  to the Bonds
received  by the Trustee  pursuant to any right given or action  taken under the
provisions of this Article VI shall (after  payment of the costs and expenses of
the  proceedings  resulting in the collection of such moneys and of the fees and
expenses,  liabilities  and  advances  of the Issuer and the  Trustee,  it being
understood  that such payment shall not be made from any moneys already held for
the benefit of the Bondholders) be deposited in the Bond Fund, and all moneys in
the Bond Fund shall be applied as follows:

                    (i) Unless the principal of all the Bonds  Outstanding shall
               have become or been  declared  due and  payable,  all such moneys
               shall be applied:

                    First: (a) in case the principal of the Bonds shall not have
               become  due, to the  payment of the  interest in default,  in the
               order of the maturity of the installments of such interest,  with
               interest,  so far as the same may be legally enforceable,  on the
               overdue  installments  thereof at the  highest  rate borne by any
               Outstanding  Bonds,  such  payments  to be  made  ratably  to the
               persons or parties entitled  thereto,  without  discrimination or
               preference; or

                    (b) in case the  principal  of any of the Bonds  shall  have
               become due, by declaration or otherwise,  first to the payment of
               the  interest  in  default,  in the order of the  maturity of the
               installments  of such interest,  and thereafter to the payment of
               the principal of, and premium, if any, on all Bonds then due with
               interest,  so far as the same may be legally enforceable,  on the
               overdue interest and principal (including premium) at the highest
               rate borne by any Outstanding Bonds, such payments, respectively,
               to be made  ratably to the persons or parties  entitled  thereto,
               without discrimination or preference.

                    Second:  to the  payment  of the  fees,  counsel  fees,  and
               advances and expenses of the Trustee and of the receiver, if any,
               and all costs and disbursements  allowed by the court if there be
               any  court  action,   and  all  other  Trustee  expenses  accrued
               hereunder.

                    Third: to the payment of the Issuer's counsel fees and other
               expenses, if any.

                    Fourth:  to the payment of the surplus,  if any, to whomever
               is  lawfully  entitled  to  receive  the  same or as a  court  of
               competent jurisdiction may direct.

                    (ii) If the  principal  of all the  Outstanding  Bonds shall
               have become due or shall have been declared due and payable,  all
               such moneys shall be applied  first to the payment of any amounts
               owed to the Trustee;  and second to the payment of the principal,
               premium,  if any,  and interest  then due on such Bonds,  without
               preference  or priority of principal and premium over interest or
               of interest over principal and premium,  or of any installment or
               interest over any other  installment of interest,  or of any Bond
               over any  other  Bond,  ratably,  according  to the  amounts  due
               respectively for principal, premium, if any, and interest, to the
               persons  entitled   thereto,   without  any   discrimination   or
               privilege.

                    (iii) If the  principal of all the  Outstanding  Bonds shall
               have been declared due and payable by  acceleration,  and if such
               declaration  shall  thereafter  have been  rescinded and annulled
               under the provisions of this Article VI, then the moneys shall be
               applied in  accordance  with the  provisions  of  subsection  (i)
               above; provided, however, that in the event that the principal of
               all the Bonds  shall  later  become  due or be  declared  due and
               payable  by   acceleration,   the  moneys  shall  be  applied  in
               accordance with the provisions of subsection (ii) of this Section
               6.07.

     Whenever  the  Trustee  shall  apply  such  funds it shall  fix the date of
application,  which  shall be an  Interest  Payment  Date  unless it shall  deem
another date more  suitable.  The Trustee  shall give such notice of the deposit
with it of any such  moneys and of the fixing of any such  date.  Section  6.08.
Remedies  Vested in Trustee.  All rights of action  (including the right to file
proofs of claim)  under  this  Indenture  and the Bonds may be  enforced  by the
Trustee  without the  possession  of any Bond or the  production  thereof in any
trial or proceedings related thereto, and any such suit or proceeding instituted
by the Trustee shall be brought in its name as Trustee  without the necessity of
joining as plaintiff or defendant the Owner of any Bond.

     Section  6.09.  Rights and  Remedies of Bond  Owners.  No Owner of any Bond
shall have any right to institute any suit, action or proceeding in equity or at
law for the  enforcement  of this  Indenture  or for the  execution of any trust
hereof or for the  appointment  of a  receiver  or any other  remedy  hereunder,
unless:

                    (i) an Event of Default  has  occurred  of which the Trustee
               has been notified as provided in Section  7.01(h)  hereof,  or of
               which by said  Section  7.01(h)  the  Trustee  is  deemed to have
               notice;

                    (ii) the Owners of not less than 25% in aggregate  principal
               amount of the Bonds  then  Outstanding  shall  have made  written
               request  to the  Trustee  and shall have  offered  it  reasonable
               opportunity  either to proceed to exercise the powers hereinabove
               granted or to institute  such action,  suit or  proceeding in the
               name or names of such  Owners,  and  shall  have  offered  to the
               Trustee indemnity as provided in Section 7.01(1) hereof; and

                    (iii)  the  Trustee  shall  thereafter  fail  or  refuse  to
               exercise the powers  hereinbefore  granted,  or to institute such
               action,  suit or proceeding  in its own name within 60 days;  and
               such  notification,  request  and offer of  indemnity  are hereby
               declared  in every  case,  at the  option of the  Trustee,  to be
               conditions precedent to the execution of the powers and trusts of
               this  Indenture,  and to any  action or cause of  action  for the
               enforcement  of  this  Indenture,  or for  the  appointment  of a
               receiver or for any other remedy hereunder. No one or more Owners
               of the Bonds  shall  have any right in any manner  whatsoever  to
               affect,  disturb or prejudice the lien of this  Indenture by such
               Owners' action,  and all proceedings at law or in equity shall be
               instituted,  had and maintained in the manner herein provided and
               (except as herein  otherwise  provided) for the equal and ratable
               benefit of the Owners of all Bonds then  Outstanding.  Nothing in
               this Indenture,  however, shall affect or impair the right of any
               Owner to enforce the payment of the  principal  of,  premium,  if
               any,  and  interest  on any Bond owned by such Owner at and after
               the maturity thereof,  or the obligation of the Issuer to pay the
               principal  of,  premium,  if any, and interest on any Bond to the
               owner thereof at the time and place, from the source,  and in the
               manner expressed in such Bond.  Nothing contained herein shall be
               construed as  permitting  or affording any Owner a right or cause
               of action  against the Trustee or in respect of the Bonds where a
               default has been waived under  Section 6.11 hereof or cured under
               Section 6.12 hereof.

     Section 6.10.  Termination of  Proceedings.  In case the Trustee shall have
proceeded  to enforce any right under this  Indenture  by the  appointment  of a
receiver or otherwise,  and such  proceedings  shall have been  discontinued  or
abandoned  for any  reason,  or shall  have  been  determined  adversely  to the
Trustee,  then and in every such case the  Issuer,  the  Trustee  and the Owners
shall be  restored  to their  former  positions  and rights  hereunder,  and all
rights,  remedies  and  powers  of the  Trustee  shall  continue  as if no  such
proceedings had been taken.

     Section  6.11.  Waivers of Events of  Default.  The  Trustee  may waive any
default or Event of Default  hereunder and its consequences and shall do so upon
the written request of the Owners of a majority in aggregate principal amount of
the Bonds then Outstanding, provided, however, that the Trustee may not waive an
Event of Default  described in subparagraphs  (i), (ii) or (iii) of Section 6.01
hereof without the written consent of the Owners of all of the Bonds.

     Section 6.12. Notice of Default; Opportunity to Cure Defaults. (a) Anything
herein to the contrary notwithstanding, no default under Section 6.01(iv) hereof
shall  constitute  an Event of Default  hereunder  until  actual  notice of such
default by  registered  or  certified  mail shall be given to the Issuer and the
Agent by the Trustee or the Owners of not less than 25% in  aggregate  principal
amount of all Bonds  Outstanding,  and the Issuer and the Company shall have had
90 days after receipt of such notice,  at their option,  to correct said default
or to cause said  default to be  corrected,  and shall not have  corrected  said
default or caused said default to be  corrected  within the  applicable  period;
provided,  however,  that if said default be such that it can be corrected,  but
cannot be corrected  within the  applicable  period,  it shall not constitute an
Event of  Default  if  corrective  action is  instituted  by the  Issuer and the
Company,  or either of them, within the applicable period and diligently pursued
until the default is corrected.

                    (b) Upon the  occurrence  of an Event of Default or upon the
               giving  of  written  notice  to the  Issuer  and the  Agent  of a
               default,  the Trustee  shall give notice  thereof by  first-class
               mail to the Owners of all Bonds then  Outstanding and, subject to
               Section  7.03  hereof,  to  persons  or  entities  which  provide
               evidence acceptable to the Trustee that such person or entity has
               legal or beneficial  interest in at least $1,000,000 in principal
               amount of Bonds.

                    (c) With regard to any default  concerning  which  notice is
               given under the provisions of this Section 6.12,  the Issuer,  to
               the full extent  permitted by law, hereby grants the Company full
               authority  to perform  and  observe for the account of the Issuer
               any  covenants or  obligation  alleged in said notice not to have
               been  performed  or  observed in the name and stead of the Issuer
               with  full  power to do any and all  things  and acts to the same
               extent  that the Issuer  could do and perform any such things and
               acts, with power of substitution.  The Trustee hereby consents to
               such grant of authority.

     Section 6.13.  Payments under Municipal Bond Insurance  Policy.  So long as
the  Municipal  Bond  Insurance  Policy  shall be in full force and effect,  the
Issuer and the Trustee hereby agree to comply with the following provisions:

                    (a) If the  Trustee  has notice  that any owner of the Bonds
               has been  required to disgorge  payments of principal or interest
               on the Bonds to a trustee in  bankruptcy  or  creditors or others
               pursuant to a final judgment by a court of competent jurisdiction
               that such payment constitutes a voidable preference to such owner
               of Bonds within the meaning of any  applicable  bankruptcy  laws,
               then the Trustee  shall  notify Bond  Insurer or its  designee of
               such  fact  by  telephone,  facsimile,  telecopy  or  telegraphic
               notice, confirmed in writing by registered or certified mail.

                    (b) the Trustee is hereby irrevocably designated, appointed,
               directed and authorized to act as attorney-in-fact  for owners of
               the Bonds as follows:

                    (i) If and to the extent  there is a  deficiency  in amounts
               required  to pay  interest on the Bonds,  the  Trustee  shall (A)
               execute and deliver to State Street Bank and Trust Company, N.A.,
               or its successors  under the Municipal Bond Insurance Policy (the
               "Insurance Paying Agent"),  in form satisfactory to the Insurance
               Paying Agent, an instrument  appointing Bond Insurer as agent for
               such  owners in any legal  proceeding  related to the  payment of
               such interest and an assignment to Bond Insurer of the claims for
               interest to which such  deficiency  relates and which are paid by
               Bond Insurer,  (B) receive as designee of the  respective  owners
               (and  not  as  Trustee)  in  accordance  with  the  tenor  of the
               Municipal Bond Insurance Policy payment from the Insurance Paying
               Agent with respect to the claims for  interest so  assigned,  and
               (C) disburse the same to such respective owners; and

                    (ii)  If  and to  the  extent  of a  deficiency  in  amounts
               required to pay  principal  of the Bonds,  the Trustee  shall (A)
               execute  and  deliver  to the  Insurance  Paying  Agent  in  form
               satisfactory   to  the  Insurance   Paying  Agent  an  instrument
               appointing  Bond  Insurer  as agent  for such  owner in any legal
               proceeding  relating  to the  payment  of such  principal  and an
               assignment to Bond Insurer of any of the Bonds surrendered to the
               Insurance Paying Agent of so much of the principal amount thereof
               as has not previously  been paid or for which moneys are not held
               by  the  Trustee  and   available  for  such  payment  (but  such
               assignment  shall be delivered only if payment from the Insurance
               Paying  Agent  is  received),  (B)  receive  as  designee  of the
               respective owners (and not as the Trustee) in accordance with the
               tenor of the Municipal  Bond Insurance  Policy  payment  therefor
               from the  Insurance  Paying  Agent,  and (C) disburse the same to
               such owners.

                    (c)  Payments  with  respect to claims for  interest  on and
               principal of Bonds  disbursed by the Trustee from proceeds of the
               Municipal  Bond  Insurance  Policy  shall  not be  considered  to
               discharge  the  obligation  of the  Issuer  or the  Company  with
               respect to such Bonds, and Bond Insurer shall become the owner of
               such unpaid Bonds and claims for the interest in accordance  with
               the tenor of the  assignment  made to it under the  provisions of
               this subsection or otherwise.

                    (d)  Irrespective of whether any such assignment is executed
               and  delivered,  Issuer  and the  Trustee  hereby  agree  for the
               benefit of Bond Insurer that:

                    (i) To the extent Bond Insurer makes  payments,  directly or
               indirectly  (as by paying  through  the  Trustee),  on account of
               principal  of or  interest  on the Bonds,  Bond  Insurer  will be
               subrogated  to the rights of such owners to receive the amount of
               such  principal  and  interest  from the  Issuer,  with  interest
               thereon as provided  and solely  from the sources  stated in this
               Indenture and the Bonds; and

                    (ii) They will  accordingly  pay Bond Insurer the amounts of
               such  principal  and interest  (including  principal and interest
               recovered under  subparagraph  (ii) of the first paragraph of the
               Municipal Bond  Insurance  Policy,  which  principal and interest
               shall be deemed past due and not have been paid),  with  interest
               thereon as provided  in this  Indenture  and the Bonds,  but only
               from  the  sources  and in the  manner  provided  herein  for the
               payment of principal of and interest on the Bonds to owners,  and
               will otherwise  treat Bond Insurer as the owner of such rights to
               the amount of such principal and interest.



                                                        
                                   ARTICLE VII

                                   THE TRUSTEE

     Section 7.01.  Acceptance of Trust.  The Trustee  hereby accepts the trusts
imposed upon it by this Indenture,  and agrees to perform said trusts,  but only
upon and subject to the following express terms and conditions:

                    (a) The  Trustee,  prior  to the  occurrence  of an Event of
               Default  and after the  curing or waiver of all Events of Default
               which may have  occurred,  undertakes  to perform such duties and
               only such duties as are  specifically set forth in this Indenture
               and no implied  covenants or obligations  shall be read into this
               Indenture  against the Trustee.  Subject to the limitation on the
               liability of the Trustee contained in Section 7.01(g), in case an
               Event of  Default  has  occurred  of which the  Trustee is deemed
               hereunder to have knowledge (which has not been cured or waived),
               the Trustee  shall  exercise such of the rights and powers vested
               in it by this  Indenture,  and use the  same  degree  of care and
               skill in their  exercise,  as a prudent man would exercise or use
               under the circumstances in the conduct of his own affairs.

                    (b) The  Trustee  may  execute  any of the  trusts or powers
               hereof and  perform  any of its  duties by or through  attorneys,
               agents,  receivers or employees,  but shall not be answerable for
               the  conduct  of the same if chosen  with due care.  The  Trustee
               shall  be  entitled  to  advice  of  counsel  of  its   selection
               concerning all matters of trust hereof and the duties  hereunder,
               and in  all  cases  may  pay  such  reasonable  compensation  and
               expenses to all such attorneys,  agents,  receivers and employees
               as may  reasonably  be  employed  in  connection  with the  trust
               hereof.  The  Trustee  may act upon the  opinion or advice of any
               attorneys  approved by the Trustee in the exercise of  reasonable
               care. The Trustee shall not be responsible for any loss or damage
               resulting  from any action or non-action  exercised in good faith
               in reliance upon such opinion or advice.

                    (c) The  Trustee  shall not be  responsible  for any recital
               herein  or  in  the  Bonds   (other  than  the   certificate   of
               authentication thereon), the legality, sufficiency or validity of
               this  Indenture,  the  Agreement,  the Bonds or any  document  or
               instrument  relating  thereto;  the  recording  or  filing of any
               instrument  required  by this  Indenture  to  secure  the  Bonds;
               insuring the Project or collecting  any insurance  proceeds;  the
               validity of the  execution by the Issuer of this  Indenture or of
               any supplement hereto or of any instrument of further  assurance;
               or the  validity,  priority,  perfection  or  sufficiency  of the
               security for the Bonds issued hereunder or intended to be secured
               hereby,  or  otherwise  as to the  maintenance  of  the  security
               hereof,   except  for  the  filing  of  Uniform  Commercial  Code
               continuation  statements  as  directed  in  writing by and at the
               expense of, the Company pursuant to Section 3.05 hereof.

                    (d) The Trustee shall not be accountable  for the use of any
               Bonds  authenticated  or  delivered  hereunder  or for the use or
               application by the Company of any moneys disbursed by the Trustee
               in accordance with the provisions hereof. To the extent permitted
               by law, the Trustee may in good faith buy, sell, own and hold any
               of the Bonds and may join in any action  which any Bond Owner may
               be entitled to take with like effect as if the Trustee were not a
               party to this  Indenture.  The  Trustee  may also engage in or be
               interested in financial or other  transactions with the Issuer or
               the Company;  provided,  however,  that if the Trustee determines
               that any such  relationship  is in conflict with its duties under
               this  Indenture,  it shall  eliminate  the  conflict or resign as
               Trustee.  To the extent  permitted  by law,  the Trustee may also
               purchase Bonds with like effect as if it were not the Trustee.

                    (e) The Trustee  shall be protected in acting upon,  and may
               conclusively  rely upon,  any  notice,  request or other paper or
               document  reasonably  believed  to be genuine  and  correct,  and
               reasonably  believed  to have been  signed or sent by the  proper
               person or persons.  Any action  taken by the Trustee  pursuant to
               this  Indenture  upon the  request,  authority  or consent of any
               person  who at the time of making  such  request  or giving  such
               authority  or  consent  is  the  Owner  of  any  Bond,  shall  be
               conclusive  and binding  upon all future  Owners of the same Bond
               and any Bond issued in replacement therefor.


                    (f) As to the existence or  nonexistence  of any fact, or as
               to the  sufficiency  or  validity  of any  instrument,  paper  or
               proceeding,  the  Trustee  shall  be  entitled  to  rely  upon  a
               certificate  signed by a duly  authorized  representative  of the
               Issuer or the Company as sufficient evidence of the facts therein
               contained;  and prior to the occurrence of a default of which the
               Trustee has been notified as provided in  subsection  (h) of this
               Section 7.01, or of which by said  subsection (h) it is deemed to
               have  notice,  shall  also be at  liberty  to  accept  a  similar
               certificate   to  the  effect   that  any   particular   dealing,
               transaction or action is necessary or expedient.  The Trustee may
               at its discretion  secure such further  evidence deemed necessary
               or  advisable,  but shall in no case be bound to secure the same.
               The  Trustee may accept a  certificate  of an  Authorized  Issuer
               Representative  to the  effect  that  a  resolution  in the  form
               therein  set forth  has been  adopted,  and is in full  force and
               effect.

                    (g) The right of the  Trustee to perform  any  discretionary
               act  enumerated  in this  Indenture  shall not be  construed as a
               duty.  The  Trustee  shall not be  answerable  for other than its
               negligence or willful misconduct in the performance of its powers
               and duties under this Indenture.

                    (h) The  Trustee  shall not be required to take notice or be
               deemed  to  have  notice  of any  default  or  Event  of  Default
               hereunder,  or in any other  document or  instrument  executed in
               connection  with the execution and delivery of the Bonds,  except
               an Event of Default under Section  6.01(i),  (ii) or (iii) hereof
               or Section  6.01(a),  (b),  or (c) of the  Agreement,  unless the
               Trustee shall be specifically notified in writing of such default
               or Event of Default by the  Issuer,  the Company or the Owners of
               at least 25% in  aggregate  principal  amount  of the Bonds  then
               Outstanding.  All notices or other  instruments  required by this
               Indenture to be  delivered  to the Trustee  shall be delivered at
               the principal corporate trust office of the Trustee,  and, in the
               absence of such notice so delivered, the Trustee may conclusively
               assume there is no default except as aforesaid.

                    (i) At any and all  reasonable  times,  the  Trustee and its
               duly   authorized   agents,   attorneys,    experts,   engineers,
               accountants and  representatives  shall have the right to inspect
               fully all books,  papers and records of the Issuer  pertaining to
               the Agreement  and the Bonds,  and to take such  photocopies  and
               memoranda therefrom and in regard thereto as may be desired.

                    (j) The  Trustee  shall not be  required to give any bond or
               surety in respect of the execution of the trust created hereby or
               the powers granted hereunder.

                    (k)  Notwithstanding  anything  contained  elsewhere in this
               Indenture,  the  Trustee  shall  have  the  right,  but  not  the
               obligation,  to  demand,  in  respect  of the  withdrawal  of any
               amount, the release of any property,  or the taking of any action
               whatsoever  within the purview of this  Indenture,  any  showing,
               certificate,   opinion,   appraisal  or  other  information,   or
               corporate  action  or  evidence  thereof,  in  addition  to  that
               required by the terms hereof as a condition of such action by the
               Trustee, as deemed desirable for the purposes of establishing the
               right of the  Issuer  or the  Company  to the  withdrawal  of any
               amount,  the  release of any  property or the taking of any other
               action by the Trustee.

                    (l) Before  taking any action  referred  to in Article VI or
               Section 7.04 hereof (except with respect to making payment on the
               Bonds  when due,  acceleration  of the Bonds and  payment  of the
               Bonds upon such  acceleration),  the Trustee  may require  that a
               satisfactory indemnity bond be furnished for the reimbursement of
               all  expenses  which it may incur and to protect  it against  all
               liability, except liability which is adjudicated to have resulted
               from its  negligence  or  willful  misconduct,  by  reason of any
               action so taken.

                    (m) All moneys  received by the Trustee  shall,  until used,
               applied or invested as herein provided,  be held in trust for the
               purposes for which they were  received but need not be segregated
               from other  funds,  except to the extent  required by law or this
               Indenture.  The Trustee  shall be under no liability for interest
               on any moneys received hereunder.

                    (n)  Notwithstanding the effective date of this Indenture or
               anything to the  contrary in this  Indenture,  the Trustee  shall
               have no liability or responsibility for any act or event relating
               to this  Indenture  which  occurs  prior to the date the  Trustee
               formally  executes this Indenture and commences acting as Trustee
               hereunder.
                                                       
                    (o) Upon the execution of this Indenture,  the 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 Indenture.

                    (p) No  provision  of this  Indenture  shall  be  deemed  to
               require the Trustee 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 its rights or powers, if
               the Trustee  shall have  reasonable  grounds for  believing  that
               repayment  of  such  funds  or,  in  the  alternative,   adequate
               indemnity  against  such  risk  or  liability  is not  reasonably
               assured to it.
                                                        
                    (q)  The  Trustee  has no  obligation  or  liability  to the
               Bondholders for the payment of interest or premium, if any, on or
               principal of the Bonds, but rather the Trustee's sole obligations
               are to  administer,  for  the  benefit  of the  Company  and  the
               Bondholders,   the  various   Funds  and   Accounts   established
               hereunder.

                    (r) In the event the Trustee shall receive  inconsistent  or
               conflicting  requests  and  indemnity  from two or more groups of
               Bondholders,  each  representing  less  than  a  majority  of the
               aggregate  principal  amount of the Bonds then  Outstanding,  the
               Trustee shall not be required to take any action hereunder.

                    (s)  Except  for   information   provided   by  the  Trustee
               concerning the Trustee,  the Trustee shall have no responsibility
               with  respect to any  information  in any  Official  Statement or
               other disclosure material  distributed with respect to the Bonds.
               The Trustee  shall have no  responsibility  for  compliance  with
               securities laws in connection with issuance of the Bonds.

                    (t) The Trustee's immunities and protections from liability,
               and its right to payment of compensation and  indemnification  in
               connection with  performance of its duties and obligations  under
               the  Indenture  and the  Agreement,  shall  survive the Trustee's
               resignation or removal, or the final payment of the Bonds.

                    (u) In acting or omitting to act pursuant to the  provisions
               of the  Agreement,  the  Trustee  shall be entitled to all of the
               rights,  protections and immunities accorded to the Trustee under
               the terms of this  Indenture,  including but not limited to those
               set out in this Article VII.

     Section  7.02.  Fees,  Charges and Expenses of Trustee.  (a) The Issuer has
agreed  with the  Company  in the  Agreement  that,  as part of the  Installment
Payments  the Company  shall pay to the Trustee its charges for  performing  the
duties of Trustee, Bond Registrar,  and Paying Agent for the Bonds. It is agreed
by the Trustee  that the Company may,  without  causing or creating a default or
Event of Default  hereunder,  contest in good faith (and withhold payment of the
contested  amount until such contest is resolved) the  reasonableness  of any of
the  foregoing  charges  for  service.  All  payments  due the  Trustee for such
charges, fees, or expenses shall be paid by the Company upon prompt presentation
of an invoice  therefor and no such charges,  fees, or expenses shall be charged
against or be payable by the Issuer.  Until the Trustee is paid in full pursuant
to its final  notice,  the rights of the Trustee  under this  Section 7.02 shall
survive the payment in full of the Bonds and the discharge of this Indenture.

                    (b) In any suit for the  enforcement  of any right or remedy
               under this  Indenture  or in any suit against the Trustee for any
               action  taken  or  omitted  by it as a  Trustee,  a court  in its
               discretion  may require  the filing by any party  litigant in the
               suit of an  undertaking  to pay the  costs of the  suit,  and the
               court in its discretion may assess  reasonable  costs,  including
               reasonable  attorney's  fees  and  expenses,  against  any  party
               litigant  in the suit,  having  due regard to the merits and good
               faith of the claims or defenses made by the party litigant.  This
               Section does not apply to a suit by the Trustee or the Issuer,  a
               suit by an Owner  pursuant to  enforcement  of the payment of the
               principal  of or interest  hereunder  or a suit by Owners of more
               than 10% in principal amount of the then Outstanding Bonds.

     Section  7.03.  Trustee to Provide  Additional  Notices.  (a) Upon  written
request  of any  Owner of Bonds in an  aggregate  principal  amount  of at least
$1,000,000 (or any person or entity which provides written  evidence  acceptable
to the Trustee that such person or entity has a legal or beneficial  interest in
Bonds in an  aggregate  principal  amount of at least  $1,000,000),  the Trustee
shall give an  additional  copy of any notice to be given by the  Trustee  under
this  Indenture by first-class  mail to a second address  specified by such Bond
Owner,   person  or  entity.   Any  such  additional   notices  shall  be  given
simultaneously with the original notices.

                    (b) Upon  written  request  of any  person or  entity  which
               provides  evidence  acceptable to the Trustee that such person or
               entity has a legal or beneficial  interest in at least $1,000,000
               in  principal  amount of the  Bonds,  the  Trustee  shall for the
               calendar  year in which such  request is received  provide one or
               more of the following as requested to such person or entity:  (i)
               notices of redemption  pursuant to Section 2.06;  (ii) notices of
               default pursuant to Section 6.12(b);  (iii) copies of all notices
               to which such person or entity is entitled under the Indenture to
               a specific second address pursuant to Section  7.03(a);  and (iv)
               outstanding balances by maturity,  redemption history,  including
               redemption date, amount and sources of funds, and distribution of
               the call to maturity.
                                                

     Section 7.04.  Intervention by Trustee. In any judicial proceeding to which
the Issuer or the  Company is a party,  and which in the  opinion of the Trustee
and its  counsel has a  substantial  bearing on the  interests  of Owners of the
Outstanding  Bonds,  the  Trustee may  intervene  on behalf of the Owners of the
Bonds and shall do so if  requested  in writing by the Owners of at least 25% in
aggregate principal amount of the Bonds then Outstanding, and when provided with
sufficient indemnity pursuant to Section 7.01(1) hereof.

     Section 7.05. Successor Trustee by Merger.  Subject to Section 7.11 hereof,
any  corporation  or  association  into which the  Trustee may be  converted  or
merged,  with which it may be consolidated,  or to which it may sell or transfer
its trust  business and assets as a whole or  substantially  as a whole,  or any
corporation or association  resulting from any such  conversion,  sale,  merger,
consolidation  or transfer to which it is a party,  ipso facto,  shall (if it is
qualified  to be Trustee  hereunder)  be and become the  Trustee  hereunder  and
vested  with all of the title to the Trust  Estate and all the  trusts,  powers,
discretions, immunities, privileges, responsibilities, obligations and all other
matters  as  was  its  predecessor,  without  the  execution  or  filing  of any
instrument  or any further  act,  deed or  conveyance  on the part of any of the
parties hereto.

     Section  7.06.  Resignation  by  Trustee.  The  Trustee may resign from the
trusts hereby created by giving written notice to the Issuer,  the Agent and the
Owners of the Bonds then Outstanding,  and shall so resign whenever it ceases to
be qualified to act as Trustee hereunder. Such notice may be sent by first class
mail,  postage  prepaid,  to the Owners of the  Bonds,  and by  certified  mail,
postage prepaid, to the Issuer and the Agent. Such resignation shall take effect
only upon the  appointment of a successor  Trustee.  If no successor  Trustee is
appointed  pursuant to Section 7.08 hereof  within 30 days after the delivery of
such notice,  a temporary  Trustee may be  appointed by the Issuer,  pursuant to
Section 7.08 hereof.  If no successor  Trustee or temporary Trustee is appointed
within 45 days after delivery of such notice, the resigning Trustee may petition
any court of competent jurisdiction for the appointment of a successor Trustee.

     Section 7.07. Removal of Trustee. The Trustee may be removed at any time by
an instrument or substantially  concurrent  instruments in writing  delivered to
the  Trustee  and the Bond  Owners and signed by the Issuer and the Agent.  Such
removal shall take effect only upon the appointment of a successor Trustee.

     Section 7.08.  Appointment of Successor Trustee.  In case the Trustee shall
resign, be removed, be dissolved, be in the course of dissolution or liquidation
or otherwise become incapable of acting or not qualified to act hereunder, or in
case the  Trustee  shall be taken  under the  control of any  public  officer or
officers or a receiver appointed by a court, a successor may be appointed by the
Issuer with the consent of the Agent.

     Section 7.09.  Successor  Trustee by Appointment.  Every successor  Trustee
appointed  hereunder shall execute,  acknowledge and deliver to its predecessor,
the Agent and the Issuer an instrument  in writing  accepting  such  appointment
hereunder,  and  thereupon  such  successor,  without any further  act,  deed or
conveyance, shall become fully vested with the title to the Trust Estate and all
of the trust  powers,  discretions,  immunities,  privileges,  responsibilities,
obligations  and all other  matters  of its  predecessor;  but such  predecessor
shall,  nevertheless,  on the written request of the Issuer, or of its successor
Trustee,  execute  and  deliver an  instrument  transferring  to such  successor
Trustee  all  the  estates,  properties,  rights,  powers  and  trusts  of  such
predecessor   hereunder;   and  every  predecessor  Trustee  shall  deliver  all
securities  and  moneys  held  by it  hereunder  to its  successor.  Should  any
instrument in writing from the Issuer be required by any  successor  Trustee for
more fully and certainly vesting in such successor the estates,  rights,  powers
and duties  hereby vested or intended to be vested in the  predecessor,  any and
all such instruments in writing shall, on request, be executed, acknowledged and
delivered by the Issuer.  The  resignation  of any Trustee and the instrument or
instruments removing any Trustee and appointing a successor hereunder,  together
with all other  instruments  provided for in this  Article  VII,  shall be filed
and/or  recorded by the successor  Trustee in each  recording  office where this
Indenture shall have been filed and/or  recorded.  No appointment of a successor
Trustee  hereunder  shall  become  effective  unless  such  successor  meets the
qualifications set forth in Section 7.11.

     Section 7.10.  Appointment  of Separate  Trustee or  Co-Trustee.  It is the
intent of the parties to this Indenture that there shall be no violations of any
law of any jurisdiction  (including  particularly the laws of the State) denying
or restricting  the rights of banking  corporations  or associations to transact
business as a trustee in such  jurisdiction.  It is  recognized  that in case of
litigation under this Indenture, and in particular in the case of enforcement of
this  Indenture on default,  or in case the Trustee  deems that by reason of any
present or future law of any jurisdiction it may not exercise any of the powers,
rights  or  remedies  herein  granted  to the  Trustee,  or  hold  title  to the
properties,  in trust, as herein granted,  or take any other action which may be
desirable or  necessary  in  connection  therewith,  it may be  necessary  that,
subject to the  qualifications  set forth in Section  7.11  hereof,  the Trustee
appoint an  additional  institution  as a separate  trustee or  co-trustee.  The
following provisions of this Section 7.10 are adapted to these ends.

     If the Trustee appoints an additional  institution as a separate trustee or
co-trustee, each and every remedy, power, right, claim, demand, cause of action,
immunity,  estate,  duty,  obligation,  title,  interest  and lien  expressed or
intended by this  Indenture  to be  exercised  by,  vested in or conveyed by the
Trustee with respect  thereto shall be exercisable by, vested in and conveyed to
such separate trustee or co-trustee,  but only to the extent necessary to enable
such  separate  trustee  or  co-trustee  to  exercise  such  powers,  rights and
remedies,  and every covenant and obligation  necessary for the exercise thereby
by such separate trustee or co-trustee shall run to and be enforceable by either
of them.

     Should  any  instrument  in  writing  from the  Issuer be  required  by the
separate  trustee or  co-trustee  so  appointed  by the  Trustee  for more fully
vesting in and  confirming  to them such  properties,  rights,  powers,  trusts,
duties  and  obligations,  any and all such  instruments  in writing  shall,  on
request, be executed,  acknowledged and delivered by the Issuer. If any separate
trustee or co-trustee,  or a successor to either, shall die, become incapable of
acting  or not  qualified  to  act,  resign  or be  removed,  all  the  estates,
properties,  rights,  powers,  trusts,  duties and  obligations of such separate
trustee  or  co-trustee,  so far as  permitted  by  law,  shall  vest  in and be
exercised by the Trustee until the  appointment  of a successor to such separate
trustee or co-trustee.

     The appointment of any separate  trustee or co-trustee  shall be subject to
written approval of the Agent so long as no Event of Default has occurred and is
continuing under this Indenture.

     Section 7.11. Qualifications. (a) Each successor to the Trustee pursuant to
Sections 7.05 and 7.09 hereof and each separate  trustee or co-trustee  (if any)
pursuant to Section 7.10 shall at all times be a bank or trust company which (i)
is organized as a corporation  or banking  association  and doing business under
the laws of the United States or any state  thereof,  (ii) is  authorized  under
such laws to  exercise  corporate  trust  powers and to  perform  all the duties
imposed  upon it by this  Indenture  and the  Agreement,  (iii)  is  subject  to
supervision  or  examination  by federal or state  authority,  (iv) has combined
capital  and  surplus  (as set  forth in its most  recent  published  report  of
condition)  of at least  $50,000,000,  (v) shall not have  become  incapable  of
acting or have been  adjudged a bankrupt or an insolvent nor have had a receiver
appointed for itself or for any of its property,  nor have had a public  officer
take  charge or control of it or its  property  or  affairs  for the  purpose of
rehabilitation,  conservation  or  liquidation  and (vi) must be an  institution
rated at least  "Baa3" by  Moody's  (or  Moody's  shall  have  provided  written
evidence that such successor Trustee is otherwise  acceptable to Moody's) if the
Bonds are then  rated by  Moody's,  and at least  "BBB-" or "A-3" by S&P (or S&P
shall have provided  written  evidence that such successor  Trustee is otherwise
acceptable to S&P) if the Bonds are then rated by S&P.

                    (b) Should the Trustee or any separate trustee or co-trustee
               at any time cease to be eligible,  pursuant to this Section 7.11,
               to act as Trustee or  co-trustee  (as the case may be),  it shall
               promptly notify the Owners of all Outstanding  Bonds,  the Issuer
               and the Agent of such fact.  Any such notice  shall set forth all
               the relevant facts known to the Trustee.

     Section 7.12.  Paying Agent. All provisions of this Article VII shall apply
with equal  force and effect to the Paying  Agent named  hereunder,  and, to the
extent  applicable,  the Paying Agent shall comply with the  provisions  of this
Article VII.

                                                      
                                  ARTICLE VIII

                              THE REMARKETING AGENT

     Section  8.01.  The  Remarketing  Agent.  At the  direction of the Company,
Morgan  Stanley  & Co.  Incorporated  is  hereby  appointed  by  the  Issuer  as
Remarketing  Agent for the Bonds. The Remarketing Agent shall act as remarketing
agent as  provided in this  Indenture,  and, in  accordance  with the  agreement
between the  Remarketing  Agent and the Company shall remarket Bonds required to
be purchased pursuant to Sections 2.10 and 2.11 hereof. The Issuer shall, at the
direction of the Agent,  appoint any successor  Remarketing Agent for the Bonds,
subject to the  conditions  set forth in Section  8.02 hereof.  The  Remarketing
Agent  shall  designate  its  principal  office to the  Trustee  and signify its
acceptance of the duties and obligations  imposed upon it hereunder by a written
instrument of acceptance delivered to the Issuer and the Trustee under which the
Remarketing Agent will agree, particularly, to:

                    (a) determine the Flexible Rates, Daily Rates, Weekly Rates,
               Monthly Rates,  Quarterly Rates,  Semiannual  Rates,  Multiannual
               Rates and Fixed Rates and give notice of such rates in accordance
               with  Section 2.02 and the form of Bond set forth in Section 2.03
               hereof;

                    (b) keep such books and records  with  respect to its duties
               as remarketing agent as shall be consistent with prudent industry
               practice; and

                    (c) remarket Bonds in accordance with this Indenture and the
               Remarketing Agreement.

     Section 8.02.  Qualifications  of Remarketing  Agent. The Remarketing Agent
shall be  authorized  by law to perform all the duties  imposed  upon it by this
Indenture.  The Remarketing Agent may resign and be discharged of the duties and
obligations created by this Indenture or may be removed, at the times and in the
manner set forth in the Remarketing  Agreement.  Any successor Remarketing Agent
shall be an institution  rated at least "Baa3" by Moody's (or Moody's shall have
provided  written  evidence that such successor  Remarketing  Agent is otherwise
acceptable  to  Moody's)  if the Bonds are then rated by  Moody's,  and at least
"BBB-" or "A-3" by S&P (or S&P shall have  provided  written  evidence that such
successor  Remarketing  Agent is otherwise  acceptable  to S&P) if the Bonds are
then rated by S&P, and  authorized by law to perform all the duties imposed upon
it by this Indenture.

     In the event of the  resignation or removal of the Remarketing  Agent,  the
Remarketing  Agent shall pay over,  assign and deliver any moneys and Bonds held
by it in such capacity to its  successor  or, if there is no  successor,  to the
Trustee.

     In the event that the Agent  should  fail to direct the Issuer to appoint a
Remarketing  Agent hereunder,  or in the event that the Remarketing  Agent shall
resign or be  removed,  or be  dissolved,  or if the  property or affairs of the
Remarketing Agent shall be taken under the control of any state or federal court
or  administrative  body because of  bankruptcy  or  insolvency or for any other
reason,  and the Agent shall not have  appointed  its  successor as  Remarketing
Agent,  the Trustee,  notwithstanding  the provisions of the first  paragraph of
this Section 8.02 shall ipso facto be deemed to be the Remarketing Agent for all
purposes of this Indenture until the appointment by the Agent of the Remarketing
Agent or successor  Remarketing  Agent, as the case may be;  provided,  however,
that the Trustee, in its capacity as Remarketing Agent, shall not be required to
sell Bonds or determine the interest rates on the Bonds or to perform the duties
set forth in Sections 2.02 and 2.03 hereof.

                                                        
                                   ARTICLE IX

                             SUPPLEMENTAL INDENTURES

     Section 9.01. Supplemental Indentures Not Requiring Consent of Bond Owners.
Subject to the terms and  provisions  of  Sections  9.03,  9.04 and 9.07 of this
Indenture,  the Issuer  and the  Trustee  may,  but shall not be  obligated  to,
without  the  consent  of, or notice to, any of the Bond  Owners,  enter into an
indenture or indentures  supplemental to this Indenture,  for any one or more of
the following purposes: (i) to cure any ambiguity,  formal defect or omission in
this  Indenture  or to make such other  changes  which shall not have a material
adverse effect upon the interests of the Bond Owners; (ii) to grant to or confer
upon the Trustee,  for the benefit of the Bond Owners,  any  additional  rights,

               satisfactorily indemnified with respect to expenses, cause notice
               of the proposed  execution of such  supplemental  indenture to be

               addresses  of such  Bond  Owners  indicated  on the  Registration
               Books.  Such  notice  shall  briefly  set forth the nature of the
               proposed  supplemental  indenture  and shall  state  that  copies
               thereof are on file at the  principal  corporate  trust office of
               the Trustee for  inspection  by all Bond  Owners.  If,  within 90

               to and  approved the  execution  thereof as herein  provided,  no
               Owner of any Bond  shall  have any  right to object to any of the
               terms and provisions  contained therein or the operation thereof,
               or in any  manner to  question  the  propriety  of the  execution
               thereof,  or to enjoin or  restrain  the  Trustee  or the  Issuer
               (subject to Section 9.04) from  executing the same or from taking
               any action pursuant to the provisions thereof. Upon the execution
               of any such supplemental indenture as in this Section and Section

                    (e) The Agent  may,  but shall not be  obligated  to,  fix a
               record date for the purpose of determining the Owners entitled to
               consent to any indenture supplemental hereto. If a record date is
               fixed,  the Owners on such record date, or their duly  designated
               proxies,  and only such  Owners,  shall be entitled to consent to
               such  supplemental  indenture,  whether or not such Owners remain
               Owners after such record date; provided, that unless such consent
               shall have become effective by virtue of the requisite percentage
               having  been  obtained  prior to the date  which is 90 days after
               such  record  date,  any  such  consent  previously  given  shall
               automatically   and  without  further  action  by  any  Owner  be
               cancelled and of no further effect.

     Section 9.03. Limitation upon Amendments and Supplements. Nothing contained

Outstanding  and affected (i) an extension of the maturity of the  principal of,
or the time for payment of any redemption  premium or interest on, any Bond or a
reduction  in the  principal  amount of any  Bond,  or the rate of  interest  or
redemption premium thereon, or a reduction in the amount of, or extension of the
time of any payment  required by, any Bond;  (ii) a privilege or priority of any
Bond over any other Bond (except as herein  provided);  (iii) a reduction in the
aggregate  principal  amount  of  the  Bonds  required  for  consent  to  such a
supplemental  indenture;  (iv) the  deprivation  of the  owner of any Bond  then
outstanding of the lien created by the  Indenture;  or (v) the amendment of this
Section  9.03.  With respect to any  amendment or  supplement to be entered into
pursuant  to Sections  9.01 or 9.02  hereof,  the  Trustee  shall be entitled to
receive a Favorable Opinion.

     Section 9.04.  Consent of Agent  Required.  Anything herein to the contrary
notwithstanding,  an amendment or  supplemental  indenture under this Article IX
shall not become  effective  unless and until the Agent shall have  consented in
writing to the execution and delivery thereof.

written agreement of the Issuer and the Company,  provided that no amendment may
be made which would materially  adversely affect the rights of the Owners of any
of the  Outstanding  Bonds  without  the  consent of the Owners of a majority in
aggregate principal amount of the Bonds then Outstanding of each Mode that would
be so  affected;  and no  amendment  may be made which  would (i)  decrease  the
amounts  payable  under  the  Agreement;  (ii)  change  the date of  payment  or
prepayment  provisions  under  the  Agreement;  or (iii)  change  the  amendment
provisions  of the  Agreement  without  the  consent of all of the Owners of the
Bonds adversely affected thereby, and provided further that the Agreement may be
amended by  written  agreement  of the  Issuer and the  Company in order to make
conforming changes with respect to amendments made to this Indenture pursuant to

of  Counsel  stating  that  the  execution  of such  supplemental  indenture  is
authorized  or  permitted by this  Indenture.  The Trustee may, but shall not be
obligated  to,  enter into any such  supplemental  indenture  which  affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

     Section 9.07. Bond Insurer to be Deemed Bondowner;  Rights of Bond Insurer;
Payments by Bond Insurer in Advance of Scheduled  Maturity Dates;  Notices.  (a)
Notwithstanding  any provision of this  Indenture to the contrary,  Bond Insurer
shall at all times be deemed the  exclusive  owner of all Bonds for the purposes
of all  approvals,  consents,  waivers,  institution  of  any  action,  and  the
direction of all remedies. No acceleration of the Bonds shall be permitted,  and
no Event  of  Default  relating  to the  Bonds  shall be  waived,  without  Bond
Insurer's consent. Subject to Section 7.01(l), Bond Insurer shall have the right
to direct all remedies pursuant to this Indenture.

                                                       
                    (b) No  amendment  or  supplement  shall  be  made  to  this
               Indenture or to the Agreement  without the prior written  consent
               of Bond Insurer to such amendment or  supplement.  A copy of such
               amendment or supplement  shall be sent by the Trustee to Standard
               & Poor's Corporation, 25 Broadway, 21st Floor, New York, New York
               10004.

                    (c) To the extent  that Bond  Insurer  makes  payment of the
               principal of or interest on the Bonds,  it shall become the owner
               of such  Bonds,  appurtenant  coupons or right to payment of such
               principal  of or  interest  on such  Bonds  and  shall  be  fully
               subrogated  to all of the  registered  owners'  rights to payment
               thereof.  To  evidence  such  subrogation  (i)  in  the  case  of
               subrogation as to claims for past due interest, the Trustee shall
               note Bond Insurer's rights as subrogee on the registration  books
               of Issuer  maintained  by the Trustee  upon receipt of proof from
               Bond Insurer as to payment of interest  thereon to the registered
               owners of the Bonds,  and (ii) in the case of  subrogation  as to
               claims  for past due  principal,  the  Trustee  shall  note  Bond
               Insurer's  rights as  subrogee on the  registration  books of the
               Issuer  maintained by the Trustee upon  surrender of the Bonds by
               the registered owners thereof to the Insurance Paying Agent.

                    (d) In the event that the  principal  of and/or  interest on
               the Bonds shall be paid by Bond Insurer  pursuant to the terms of
               the  Municipal  Bond  Insurance  Policy,  (i)  such  Bonds  shall
               continue to be Outstanding  under this Bond  Indenture,  (ii) the
               assignment  and  pledge of the Trust  Estate  and all  covenants,
               agreements  and other  obligations  of  Issuer to the  registered
               owners shall  continue to exist,  and Bond Insurer shall be fully
               subrogated  to all of the  rights  of such  registered  owners in
               accordance  with the terms and  conditions  of  subparagraph  (c)
               above and the  Municipal  Bond  Insurance  Policy,  and (iii) the
               Company shall reimburse Bond Insurer for the amounts paid by Bond
               Insurer  under the policy.  Amounts  paid to Bond Insurer as bond
               owner and  subrogee  shall,  to the  extent of such  payment,  be
               credited  against the amounts to be paid to Bond Insurer pursuant
               to clause (iii).

                    (e) In the event that Bond  Insurer  shall make any payments
               of principal of, and/or interest on, any of the Bonds pursuant to
               the terms of the Municipal Bond Insurance  Policy,  and the Bonds
               are  accelerated,  Bond  Insurer may, at any time and at its sole
               option,  pay to the  owners of the Bonds  all or any  portion  of
               amounts  due under the Bonds prior to the stated  maturity  dates
               thereof.

                    (f) Bond  Insurer  shall be  notified  (i) in advance of the
               execution of any  supplemental  indenture  and of any  amendment,
               change or  modifications of the Agreement in the event consent of
               the owners of Bonds is not required,  (ii)  immediately  upon the
               occurrence  of any Event of  Default  or of any  event  that with
               notice  and/or  with the lapse of time  could  become an Event of
               Default,  and (iii) of any  redemption  of Bonds at the same time
               that the  owners of the Bonds to be  redeemed  are  notified.  In
               addition, all notices,  reports,  certificates and opinions to be
               delivered  to or by Bond  Trustee  or to the  owners  of Bonds or
               available at the request of the owners of the Bonds shall also be
               delivered  to Bond Insurer or made  available  at Bond  Insurer's
               request, as the case may be.

                    (g) The Trustee  shall also notify Bond Insurer  immediately
               (a)  upon  the  resignation  or  removal  of the  Trustee  or the
               appointment  of a successor  Trustee and (b) upon  receiving  any
               notice  from  the  Company   pursuant  to  Section  4.06  of  the
               Agreement.  Any notice that is required to be given to the owners
               of the Bonds or to the Trustee  pursuant to this  Indenture,  any
               supplemental  indenture and the Agreement  shall also be provided
               to Bond Insurer. All notices required to be given to Bond Insurer
               under this  Indenture  shall be in  writing  and shall be sent by

               to Manager,  Surveillance Department, MBIA Insurance Corporation,

                    (h)  Notwithstanding  the foregoing,  the provisions of this
               Section  9.07  shall  apply  only so long as the  Municipal  Bond
               Insurance  Policy is in full  force and  effect but shall have no
               impact on any subrogation rights of the Bond Insurer.

between RED RIVER AUTHORITY OF TEXAS, a governmental agency and body politic and

INCORPORATED and CITICORP SECURITIES, INC. (the "Underwriters").

                  1.  Background

                    (a)  Subject to the terms and  conditions  herein set forth,
               the  Underwriters  hereby agree to purchase from the Issuer,  and
               the Issuer hereby agrees to sell and deliver to the Underwriters,
               the Issuer's  Pollution  Control  Revenue  Refunding  Bonds (West
               Texas Utilities  Company,  Public Service Company of Oklahoma and
               Central Power and Light Company  Oklaunion  Project)  Series 1996
               (the "Refunding  Bonds") in the principal  amount of $63,300,000.
               The Refunding  Bonds shall be dated,  shall mature and shall bear
               interest  from time to time at  adjustable  or fixed rates as set
               forth in Section 2 hereof and shall otherwise have such terms and
               provisions  as set forth in the  Refunding  Bonds,  the  Official
               Statement and the Indenture (as hereinafter defined).

                    (b) The  Refunding  Bonds  will be  issued  pursuant  to the
               resolution  adopted  by the Board of  Directors  of the Issuer on
               July 17, 1996 (the "Resolution"), and under an Indenture of Trust
               dated as of July 1, 1996 (the "Indenture") between the Issuer and
               The Bank of New York, as trustee (the  "Trustee").  The Refunding
               Bonds are to be issued to provide  funds for the  redemption  and
               cancellation   of  all  or  a  portion  of  the  Issuer's  7-7/8%

               Power and Light Company Oklaunion  Project) Series 1984 (the "Old
               Bonds").  The  proceeds  of the Old Bonds  were used to  acquire,
               construct and improve certain air and water pollution control and
               solid  waste  disposal   facilities  (the  "Facilities")  at  the
               Oklaunion  Electric  Generating  Plant (the  "Plant")  located in
               Wilbarger County,  Texas in which West Texas Utilities Company, a
               Texas corporation ("WTU"), Public Service Company of Oklahoma, an
               Oklahoma   corporation  ("PSO"),  and  Central  Power  and  Light
               Company,  a Texas  corporation  ("CPL" and, together with WTU and
               PSO,  collectively  the  "Companies"  and  each  individually,  a
               "Company")  owns  54.7%,  15.6%,  and 7.8%  undivided  interests,
               respectively.  In  connection  with the issuance of the Refunding
               Bonds,  the Issuer and the  Companies  and Central and South West
               Services, Inc., as agent for the Companies,  have entered into an
               Installment  Payment  Agreement  dated  as of July 1,  1996  (the
               "Installment   Agreement"),   which   obligates   the   Companies
               severally,  but  not  jointly,  to  pay  amounts  designed  to be
               sufficient to pay the principal of, premium, if any, and interest
               on the  Refunding  Bonds.  The Issuer has  assigned  the right to
               receive such payments from the Companies to the Trustee  pursuant
               to the Indenture.

                    (c)  Concurrently  with the  execution  and delivery of this
               Purchase  Agreement,  the Companies are  delivering to the Issuer
               and the Underwriters their Letter of Representation dated of even
               date herewith in substantially the form of Appendix A hereto (the
               "Letter of Representation") indicating their respective approvals
               of the  terms  and  provisions  of this  Purchase  Agreement  and
               acknowledging  that the Issuer will sell the  Refunding  Bonds to
               the Underwriters and the Underwriters will purchase the Refunding
               Bonds and make a public  offering  thereof in  reliance  upon the
               representations,  covenants  and  indemnities  contained  in  the
               Letter of Representation.

                    (d)  The   Facilities   constitute   solid  waste   disposal
               facilities  or air or  water  pollution  control  facilities  for
               purposes of Section  103(b)(4)(E) or (F) of the Internal  Revenue
               Code of 1954, as amended. The Refunding Bonds will be obligations
               described  in Section  1313 of the Tax Reform Act of 1986 so that
               interest on the  Refunding  Bonds will not be includible in gross
               income for federal tax  purposes  (except as noted in the opinion
               of Bond Counsel included as Appendix E to the Official Statement)
               and the  Underwriters  may  offer  the  Refunding  Bonds for sale
               without registration under the Securities Act of 1933, as amended
               (the  "Securities  Act"), or qualification of the Indenture under
               the Trust Indenture Act of 1939, as amended (the "Trust Act").

                    (e) A Preliminary  Official  Statement  dated July 19, 1996,
               including all Appendices  thereto and all documents  incorporated
               therein by reference (the "Preliminary Official Statement"),  has
               been prepared for use in the offering of the Refunding Bonds, and
               a final Official Statement dated as of the date hereof, including
               all Appendices thereto and all documents  incorporated therein by
               reference (the "Final Official Statement"), has been delivered by
               the Issuer to the Underwriters.  The Final Official Statement, as
               it may be amended or supplemented with the consent of the Issuer,
               the Underwriters and the Company,  is hereinafter  referred to as
               the "Official Statement."

                    (f)  MBIA   Insurance   Corporation   ("MBIA")  has  made  a
               commitment  to  issue a  municipal  bond  insurance  policy  (the
               "Municipal  Bond  Insurance  Policy")  relating to the  Refunding
               Bonds  effective  as of the  date of  issuance  of the  Refunding
               Bonds.  The Municipal Bond  Insurance  Policy will insure payment
               only as  principal  or interest  payments  become due but are not
               paid.

     2. Purchase,  Sale and Closing.  Subject to the terms and conditions herein
set forth,  the  Underwriters  agree to jointly and severally  purchase from the
Issuer,  and the Issuer agrees to sell to the  Underwriters,  Refunding Bonds in
the principal amount set forth opposite each  Underwriters's  name on Schedule I
hereto at a purchase price equal to 100% of the principal  amount thereof,  plus
accrued  interest  from July 1,  1996 through the day preceding the Closing Date

               in the Preliminary  Official  Statement and in the Final Official
               Statement  is,  and,  as  such  information  may  be  amended  or
               supplemented  as of the Closing Date will be, true and correct in
               all material  respects,  and such information does not, and as it
               may be amended or  supplemented  as of the Closing Date will not,
               include any untrue  statement of a material fact or omit to state
               a material fact necessary in order to make the  statements  under
               the caption "The Issuer" in the  Preliminary  Official  Statement
               and the  Official  Statement,  in the light of the  circumstances
               under which they were made, not misleading.

                    (b) The Issuer is a duly  constituted  and validly  existing
               governmental  agency and body politic and  corporate of the State
               of Texas,  with full legal right,  power and authority  under and
               pursuant to Chapters 30 and 383,  Texas Water Code (the "Enabling
               Legislation"),  to execute and deliver this  Purchase  Agreement,
               the Installment Agreement and the Indenture,  to sign and deliver
               the  Official   Statement,   to  carry  out  and  consummate  the
               transactions  contemplated by each of the foregoing and all other
               agreements  relating thereto,  and to issue, sell and deliver the
               Refunding  Bonds for the purpose of refunding  all or any portion
               of outstanding Old Bonds.

                    (c) The Issuer has full legal right, power and authority and
               has  taken  all  necessary  action  and  has  complied  with  all
               applicable   provisions   of  law   required  (i)  to  adopt  the
               Resolution,  (ii) to execute and deliver this Purchase Agreement,
               the Installment Agreement, the Refunding Bonds and the Indenture,
               (iii) to issue and sell the Refunding  Bonds to the  Underwriters
               pursuant  hereto and to the  Indenture  and (iv) to carry out and
               consummate all other  transactions  contemplated  by each of such
               documents,  and the  Issuer  has  complied  with  all  applicable
               provisions of law in all matters relating to such transactions.

                    (d) The Issuer has duly  authorized (i) the delivery and due
               performance of the Resolution and the execution, delivery and due
               performance   of  this  Purchase   Agreement,   the   Installment
               Agreement,  the  Refunding  Bonds and the  Indenture,  including,
               without limitation,  the issuance and sale of the Refunding Bonds
               to the  Underwriters  and  (ii)  the  taking  of any and all such
               action as may be required on the part of the Issuer to carry out,
               give effect to and consummate the  transactions  contemplated  by
               each of the foregoing.  None of the  proceedings or actions taken
               by the Issuer with  respect to any of the  Refunding  Bonds,  the
               Indenture,  the Installment  Agreement,  the Preliminary Official
               Statement, the Official Statement or this Purchase Agreement have
               been repealed,  rescinded or revoked.  The Official  Statement is
               deemed final by the Issuer for  purposes of Rule  15c2-12  ("Rule
               15c2-12")  under the Securities  Exchange Act of 1934, as amended
               (the "Exchange Act").

                    (e) The  Issuer  has not been  notified  of any  listing  or
               proposed  listing by the Internal  Revenue  Service to the effect
               that the Issuer is a bond issuer whose  arbitrage  certifications
               may not be relied upon.

                    (f) The Resolution  has been duly adopted by the Issuer,  is
               in full  force and effect and  constitutes  the legal,  valid and
               binding act of the Issuer.  This Purchase Agreement has been duly
               executed and delivered by the Issuer and  constitutes  the legal,
               valid and binding  obligation of the Issuer  enforceable  against
               the  Issuer  in  accordance  with  its  terms,   subject,  as  to
               enforcement,   to   bankruptcy,    insolvency,    reorganization,
               moratorium  or other  similar laws  relating to or affecting  the
               enforcement of creditors'  rights  generally and to the effect of
               general    principles   of   equity    (regardless   of   whether
               enforceability  is  considered  in a  proceeding  in equity or at
               law).  The  Installment  Agreement and the Indenture each will be
               duly  executed  by the  Issuer  and,  when  delivered,  each will
               constitute the legal,  valid and binding obligation of the Issuer
               enforceable  against  the  Issuer in  accordance  with its terms,
               subject,   as  to   enforcement,   to   bankruptcy,   insolvency,
               reorganization,  moratorium  or other similar laws relating to or
               affecting the enforcement of creditors'  rights  generally and to
               the effect of general principles of equity (regardless of whether
               enforceability  is  considered  in a  proceeding  in equity or at
               law).

                    (g) When  delivered to and paid for by the  Underwriters  at
               Closing  in  accordance  with  the  provisions  of this  Purchase
               Agreement, the Refunding Bonds initially delivered will have been
               duly  approved by the Attorney  General of the State of Texas and
               registered by the  Comptroller of Public Accounts of the State of
               Texas, and the Refunding Bonds will be duly authorized, executed,
               issued and delivered and will constitute  legal,  valid,  binding
               and enforceable  limited  obligations of the Issuer in accordance
               with their terms and in conformity with the Enabling  Legislation
               and  will  be  entitled  to  the  benefit  and  security  of  the
               Installment Agreement, the Resolution and the Indenture.

                    (h) No approval,  permit,  consent or  authorization  of any
               governmental  or public  agency,  authority or person not already
               obtained (other than (i) the approval of the Attorney  General of
               the State of Texas with  respect to the  Refunding  Bonds,  which
               approval  and  registration  shall be obtained on or prior to the
               Closing Date, and (ii) the registration of the Refunding Bonds by
               the  Comptroller  of  Public  Accounts  of the State of Texas and
               (iii) any order or approval of any federal or state  governmental
               agency or authority necessary to authorize WTU's, PSO's and CPL's
               respective  obligations  with respect to the Refunding Bonds, the
               Letter of Representation, the Municipal Bond Insurance Policy and
               the Installment  Agreement,  which approvals and orders are to be
               obtained by the  companies on or prior to the Closing  Date,  the
               receipt of all of which are  expressly  made a  condition  to the
               Issuer's, the Underwriters' and each of the Companies' respective
               obligations  to  issue,  purchase  and sell the  Refunding  Bonds
               hereunder and under the Letter of Representation;  and other than
               any  approvals  that  might  be  required  under  the Blue Sky or
               securities  laws of any  jurisdiction)  is required in connection
               with the issuance and sale of the Refunding  Bonds,  the adoption
               of the  Resolution or the execution and delivery by the Issuer of
               the Refunding Bonds, the Installment Agreement,  the Indenture or
               this Purchase  Agreement or the  performance  of its  obligations
               under any of such instruments.

                    (i) The adoption of the Resolution, the issuance and sale of
               the   Refunding   Bonds,   the   acceptance   of  the  Letter  of
               Representation,  the execution and delivery by the Issuer of this
               Purchase  Agreement,  the  Installment  Agreement,  the Refunding
               Bonds and the Indenture, the execution and delivery by the Issuer
               of the Official  Statement  and  compliance  with the  provisions
               hereof and thereof,  will not conflict with, violate or result in
               a breach of any  provision  of, or  constitute  a default  (or an
               event  which  with  notice or  passage  of time,  or both,  would
               constitute  a  default)  on the  part of the  Issuer  under,  any
               indenture, commitment, agreement or other instrument to which the
               Issuer is a party or by which it is bound, or under any provision
               of the Texas Constitution or any existing law, rule,  regulation,
               judgment,  ordinance, order or decree to which the Issuer (or any
               of its  directors or officers in their  respective  capacities as
               such) is subject,  or result in the creation or imposition of any
               lien,  charge or other  security  interest or  encumbrance of any
               nature whatsoever upon any of the property, assets or revenues of
               the Issuer,  except as provided  in the  Refunding  Bonds and the
               Indenture.

                    (j) The  Issuer is  solvent  and,  since its  creation,  the
               Issuer has not been in default in the  payment of  principal  of,
               premium,  if any, or interest  on, or  otherwise  been in default
               with respect to, any of its bonds,  notes or other  securities or
               any legally authorized obligation issued or guaranteed by it; and
               no  bankruptcy or  insolvency  proceedings  have been taken by or
               against the Issuer.

                    (k) Payments under the Installment Agreement, the Indenture,
               the Resolution and the Refunding  Bonds,  and the interest on the
               Refunding  Bonds,  are not  subject to  taxation  in the State of
               Texas.  No  legislation,  ordinance,  rule or regulation has been
               enacted by, or is  currently  pending  before,  any  governmental
               body,  department  or agency  of the State of Texas,  nor has any
               decision been rendered by any court of competent  jurisdiction of
               the State of Texas,  which would  adversely  affect the exemption
               from all taxation in the State of Texas of (i) any payments under
               the Installment Agreement,  the Indenture,  the Resolution or the
               Refunding  Bonds and the interest on the Refunding  Bonds or (ii)
               all  bonds  and  obligations  of  the  general  character  of the
               Refunding  Bonds.  There are no stamp,  documentary,  transfer or
               like taxes in the State of Texas which would be applicable to the
               original issuance or subsequent transfers of the Refunding Bonds.

                    (l)  There  is  no  action,  suit,  proceeding,  inquiry  or
               investigation,  at  law or in  equity,  before  or by any  court,
               public board, governmental agency or body or arbitrator,  pending
               or, to the best of the knowledge of the Issuer,  threatened  (nor
               to the best of the  knowledge  of the  Issuer  is there any basis
               therefor),  which  in  any  way  questions  the  validity  of the
               Enabling  Legislation,  the powers of the Issuer  referred  to in
               paragraphs (b)  and (c) of this Section 3 above,  or the validity
               of any  proceedings  taken by the Issuer in  connection  with the
               issuance  and  sale  of  the  Refunding   Bonds,  or  wherein  an
               unfavorable  decision,  ruling or finding might adversely  affect
               the  transactions  contemplated  hereby  or  by  the  Installment
               Agreement,  the Indenture or the Official  Statement or which, in
               any way, might adversely affect the validity or enforceability of
               the Refunding Bonds, the Resolution,  the Installment  Agreement,
               the  Indenture  or  this  Purchase  Agreement  (or of  any  other
               instrument  required or contemplated  for use in consummating the
               transactions  contemplated  thereby or  hereby) or the  exclusion
               from gross income for federal  income tax purposes of interest on
               the Refunding Bonds.

     4. Covenants and Agreements of the Issuer.  The Issuer covenants and agrees
with the Underwriters that it will:

                    (a) Furnish or cause to be furnished to the Underwriters (i)
               on the date of the  execution  of this  Purchase  Agreement,  two
               copies of the Final  Official  Statement  and, on the date of any
               amendment or supplement thereto,  two copies of such amendment or
               supplement,  prepared in a manner  consistent  with (b) below and
               (ii) on or prior to the Closing  Date,  two specimens of the form
               of Refunding Bond, two certified copies of the Resolution and two
               executed copies of the Indenture and of the Installment Agreement
               (which  documents shall be in the forms  previously  delivered to
               the  Underwriters,  subject to such  changes as the  Underwriters
               shall  approve);  the Issuer agrees that the Companies may at the
               Companies'  expense furnish to the Underwriters,  without charge,
               as many copies of the  Official  Statement  and any  amendment or
               supplement thereto as the Underwriters may reasonably request.

                    (b) Before amending or supplementing the Official Statement,
               furnish to the  Underwriters  two copies and to the Companies two
               copies of each proposed amendment or supplement.  No amendment or
               supplement  to  the  Official  Statement  will  contain  material
               information  with  respect  to the  Issuer  different  from  that
               contained in the Final  Official  Statement  which is  reasonably
               unsatisfactory to the Underwriters or the Companies.

                    (c) During such period as the Underwriters  believe delivery
               of the Official Statement is necessary or desirable in connection
               with  sales  of the  Refunding  Bonds  by the  Underwriters  or a
               dealer,  if any event  shall occur as a result of which it may be
               necessary to amend or supplement the Official  Statement in order
               to make the statements therein, in the light of the circumstances
               when the Official  Statement  is  delivered  to a purchaser,  not
               misleading, immediately notify the Underwriters and the Companies
               of such event and cooperate at the request of the Underwriters in
               the  preparation  of  amendments or  supplements  to the Official
               Statement which in the judgment of the Underwriters are necessary
               so that the statements with respect to the Issuer in the Official
               Statement as so amended or supplemented will not, in light of the
               circumstances  when the  Official  Statement  is  delivered  to a
               purchaser, be misleading.

                    (d)  Cooperate in qualifying  the Refunding  Bonds for offer
               and sale and in  determining  their  eligibility  for  investment
               under  the laws of such  jurisdictions  as the  Underwriters  may
               reasonably  request,  provided  that  the  Issuer  shall  not  be
               required to qualify to do business or consent to general  service
               of process in any state or  jurisdiction  other than the State of
               Texas.

                    (e) Apply the  proceeds  from the  issuance  and sale of the
               Refunding   Bonds  in  the  manner  set  forth  in  the  Official
               Statement,  and not take any action which will  adversely  affect
               the exclusion  from gross income for federal  income tax purposes
               of the interest on the Refunding Bonds.

                    (f)  Promptly  make or cause to be made  under  the  Uniform
               Commercial  Code of the  State  of  Texas,  or  under  any  other
               applicable law, at such times as may be required, all filings, if
               any,  required  in  order  to  establish,  maintain,  protect  or
               preserve the interest of the Trustee in the rights assigned to it
               under  the  Resolution,   the   Installment   Agreement  and  the
               Indenture.

                    (g) Refrain from knowingly  taking any action with regard to
               which the Issuer may exercise control that would result, or could
               reasonably  be expected to result,  in the loss of the  exclusion
               from gross income for federal income tax purposes of the interest
               on the  Refunding  Bonds  referred  to  under  the  caption  "Tax
               Matters" in the Official

              Statement.

     5. Survival of Representations,  Warranties and Agreements.  The respective
covenants, agreements, representations,  warranties and other statements of each
of the Issuer and the Underwriters,  as set forth in this Purchase  Agreement or
made by them pursuant to this Purchase Agreement, shall remain in full force and
effect,  regardless of any  investigation  made by or on behalf of the Issuer or
any  Underwriter or any officer,  director or controlling  person  thereof,  and
shall survive the termination of this Purchase Agreement and the delivery of and
payment for the Refunding Bonds.

     6. Conditions of Underwriters' Obligations. The Underwriters' obligation to
purchase  and  pay  for  the  Refunding  Bonds  at  Closing  is  subject  to the
performance  by the Issuer of its  obligations  and  agreements  to be performed
hereunder and under the Installment Agreement,  the Resolution and the Indenture
at or prior to  Closing  and the  performance  by each of the  Companies  of the
obligations  to be performed by each Company under the Letter of  Representation
and the  Installment  Agreement at or prior to Closing and to the fulfillment of
the following conditions at or prior to Closing:

                    (a) Each of the Companies shall have executed and the Issuer
               shall  have  accepted  the  Letter  of  Representation,  and  the
               representations  and  warranties of the Issuer herein and of each
               of the  Companies in the Letter of  Representation  shall be true
               and correct on and as of the Closing Date;

                    (b)  Each of the  Indenture  and the  Installment  Agreement
               shall have been duly  authorized,  executed and  delivered by the
               respective parties thereto and shall be in full force and effect,

                  the Official Statement, together with evidence
                  satisfactory to the Underwriters that all general
                  and special conditions to the effectiveness of the
                  Municipal Bond Insurance Policy have been
                  satisfied.

                    (f) At  Closing  there  shall  not have  been  any  material
               adverse change in the financial condition of any of the Companies
               or any adverse  development  concerning the business or assets of
               any of the  Companies  which would  result in a material  adverse
               change in the  prospective  financial  condition  or  results  of
               operations  of any Company  from that  described  in the Official
               Statement which, in the sole judgment of the Underwriters,  makes
               it inadvisable to proceed with the sale of the Refunding Bonds;

                    (g)   The   Securities   and   Exchange    Commission   (the
               "Commission")  shall  have  issued  an order  under the 1935 Act,
               authorizing  WTU's,  PSO's and CPL's respective  obligations with
               respect to the Refunding Bonds, the Letter of Representation, the
               Installment  Agreement and the Municipal Bond  Insurance  Policy,
               which  order  shall be in full  force and  effect;  the  Attorney
               General of the State of Texas shall have  examined the  Refunding
               Bonds and the  records  relating  to their  issuance,  shall have
               certified  as to their  validity  and  shall  have  approved  the
               Refunding  Bonds;  the Refunding Bonds shall have been registered
               by the Comptroller of Public Accounts of the State of Texas;  and
               the Oklahoma  Corporation  Commission  shall have issued an order
               authorizing  PSO's  obligations  with  respect  to the  Refunding
               Bonds, the Letter of Representation and the Installment Agreement
               which order shall be in full force and effect;

                    (h) All matters  relating to this  Purchase  Agreement,  the
               Official Statement, the Refunding Bonds and the sale thereof, the
               Installment Agreement, the Indenture, the Resolution,  the Letter
               of  Representation,  and  the  consummation  of the  transactions
               contemplated  hereby  or  thereby  shall be  satisfactory  to and
               approved by the  Underwriters  as of the Closing,  which approval
               shall not be unreasonably  withheld. Any certificate signed by or
               on behalf of the Issuer or any of the  Companies and delivered at
               the Closing shall be a representation  and warranty by the Issuer
               or such Company,  as the case may be, to the  Underwriters  as to
               the statements made therein;

                    (i) The Underwriters  shall have received from the Companies
               payment on the Closing Date by wire transfer of the Underwriters'
               fees (.831% of the principal  amount of the  Refunding  Bonds) as
               set forth in Section 7 of the Letter of Representation; and

                    (j) Subsequent to the dates as of which information is given
               in the Official  Statement,  there shall not have been any change
               or  decrease   specified  in  any  of  the  letters  required  by
               subsection  (e)(x) which is, in the judgment of the Underwriters,
               so material and adverse as to make it  impractical or inadvisable
               to proceed with the offering or delivery of the  Refunding  Bonds
               as contemplated in the Official Statement.

     7. Events  Permitting the  Underwriters to Terminate.  The Underwriters may
terminate  their  obligations to purchase the Refunding Bonds at any time before
Closing if any of the following occurs:


                    (a) A legislative, executive or regulatory action (including
               the   introduction  or  proposal  for  adoption  of  legislation,
               executive  orders or  regulations)  or a court decision which, in
               the sole judgment of the Underwriters,  casts sufficient doubt on
               the  legality  of,  or  the  tax-free   status  of  interest  on,
               obligations  of the general kind and  character as the  Refunding
               Bonds so as to materially  impair the marketability or materially
               lower the market price  thereof or would make it  impractical  to
               market  the  Refunding  Bonds  on the  terms  and  in the  manner
               contemplated in the Official Statement;

                    (b) Any  action by the  Commission,  any other  governmental
               agency, or a court which, directly or indirectly,  would require,
               in the reasonable judgment of the Underwriters,  (i) registration
               of  the  Refunding   Bonds  under  the  Securities  Act  or  (ii)
               qualification  of an indenture in respect of the Refunding  Bonds
               under the Trust Act, or any such action or legislative, executive
               or   regulatory   action   (including   action  by  the  Oklahoma
               Corporation  Commission)  with the purpose or effect of otherwise
               prohibiting the issuance, offering or sale of the Refunding Bonds
               as  contemplated  hereby  or  by  the  Official  Statement  or of
               obligations of the general character of the Refunding Bonds;

                    (c) (i) Any general  suspension  or material  limitation  on
               trading in  securities  on the New York Stock  Exchange or by the
               Commission  or by any federal or state  agency or by the decision
               of any court,  any  limitation  on prices for such trading or any
               restrictions on the  distribution of securities,  (ii) trading in
               any securities of any of the Companies  shall have been suspended
               by the  Commission  or a national  securities  exchange,  (iii) a
               general banking  moratorium on commercial  banking  activities in
               New York shall have been  declared  either by federal or New York
               State  authorities,  (iv) the rating  assigned by any  nationally
               recognized  securities  rating agency to any securities of any of
               the  Companies as of the date of this  Purchase  Agreement  shall
               have  been  lowered  since  that  date or (v)  there  shall  have
               occurred any outbreak or material  escalation of  hostilities  or
               other  calamity or crisis,  the effect of which on the  financial
               markets  of the  United  States  is such as to  make  it,  in the
               judgment  of  the  Underwriters,   impracticable  to  market  the
               Refunding Bonds; or

                    (d) Any event or condition not expressly contemplated in the
               Official   Statement   which,   in  the  sole   judgment  of  the
               Underwriters,  renders  untrue  or  incorrect,  in  any  material
               respect as of the time to which the same purports to relate,  the
               information, including the financial statements, contained in the
               Official  Statement,  including  Appendices thereto and documents
               incorporated  therein  by  reference,   or  which  requires  that
               information  not reflected in such Official  Statement  should be
               reflected therein in order to make the statements and information
               contained  therein not misleading in any material respect at such
               time,  which,  in  either  event,  in the  sole  judgment  of the
               Underwriters,  makes it  inadvisable  to proceed with the sale of
               the Refunding  Bonds;  provided,  however,  that the Underwriters
               shall  not  exercise  the  termination  right  provided  in  this
               subparagraph (d) (i) until the Underwriters  shall have consulted
               with the  Companies  with  respect to the event or  condition  at
               issue  and  (ii) so long as the  Companies  and the  Underwriters
               shall  reasonably  believe  that such event or  condition  can be
               eliminated or cured prior to the Closing Date.

     8. Execution in  Counterparts.  This Purchase  Agreement may be executed in
any number of counterparts, all of which taken together shall constitute one and
the same  instrument,  and any of the parties  hereto may execute this  Purchase
Agreement by signing any such counterpart.

Ladies and Gentlemen:

     1.  Introduction and Background.  Pursuant to a Bond Purchase  Agreement of
even date herewith (the  "Purchase  Agreement")  between Red River  Authority of
Texas  (the  "Issuer")  and  Morgan  Stanley  & Co.  Incorporated  and  Citicorp
Securities,  Inc.  (the  "Underwriters"),  the  Issuer has agreed to sell to the
Underwriters, and the Underwriters have jointly and severally agreed to purchase
from the Issuer and to offer for sale the bonds  described above (the "Refunding
Bonds"),  by means of the Final Official Statement of even date herewith,  as it
may be amended or supplemented with the consent of the Underwriters,  the Issuer
and West  Texas Utilities Company, a Texas corporation  ("WTU"),  Public Service
Company of Oklahoma,  an Oklahoma  corporation  ("PSO"),  and Central  Power and
Light Company,  a Texas corporation ("CPL" and, together with WTU and PSO, being
referred to herein  collectively as the "Companies" and each sometimes  referred
to herein  individually as a "Company").  The Final Official Statement describes
the  definitive  terms and  provisions  of the  Refunding  Bonds and contains in
Appendices  A,  B and  C  thereto  information  concerning  WTU,  PSO  and  CPL,
respectively,  which Appendices, including all documents incorporated therein by
reference,  shall for all purposes hereof be deemed to be a part of the Official
Statement,  all on terms approved by the  Companies.  Unless  otherwise  defined
herein,  all  capitalized  terms used herein  shall have the  meanings  assigned
thereto in the Purchase Agreement.

     Each of the Companies  hereby (i) approves the terms and  provisions of the
Purchase Agreement and of the Refunding Bonds, (ii) requests the Issuer to issue
and sell the  Refunding  Bonds and (iii)  acknowledges  that the  Issuer and the
Underwriters  are entering into the Purchase  Agreement and agreeing to sell and
purchase the Refunding Bonds on the terms and subject to the conditions  therein
set forth, in reliance on the representations,  covenants and agreements of each
of the Companies contained in this Letter of Representation.

     2.  Representations  by WTU. WTU makes the  following  representations  and
warranties, all of which shall survive the termination of the Purchase Agreement
and the sale and delivery of the Refunding Bonds to the Underwriters.

                    (a)  That  it  is  a  corporation  duly  organized,  validly
               existing  and in good  standing  under  the laws of the  State of
               Texas,  with full corporate  power and authority to engage in the
               business  and  activities  conducted  by it as  described  in the
               Official  Statement  and,  subject to the opinion of the Attorney
               General of the State of Texas  approving the Refunding  Bonds and
               the registration of the Refunding Bonds upon initial issue by the
               Comptroller of Public Accounts of the State of Texas, the receipt
               of which are  expressly  made a  condition  to WTU's  obligations
               under the Installment Agreement,  has full power and authority to
               execute and deliver and to carry out and perform its  obligations
               under  this  Letter  of   Representation   and  the   Installment
               Agreement.

                    (b) That it has duly  approved the forms of the  Resolution,
               the  Indenture  and  the  Purchase  Agreement.   The  Installment
               Agreement has been duly authorized, executed and delivered by WTU
               and is a legal,  valid and binding  obligation of WTU enforceable
               in accordance  with its terms,  subject,  as to  enforcement,  to
               bankruptcy,  insolvency,  reorganization,   moratorium  or  other
               similar laws relating to or affecting creditors' rights generally
               and to the effect of general  principles of equity (regardless of
               whether enforceability is considered in a proceeding in equity or
               at  law).  WTU has  duly  authorized  the  taking  of all  action
               necessary  to  carry  out and  give  effect  to the  transactions
               contemplated to be performed by it by the Official Statement, the
               Installment Agreement,  the Purchase Agreement and this Letter of
               Representation.  WTU expects  that the  Commission  will issue an
               order (the "Order") under the 1935 Act on or prior to the Closing
               Date  authorizing  WTU's (and PSO's and CPL's)  obligations  with
               respect  to  this  Letter  of  Representation,   the  Installment
               Agreement,  the Municipal  Bond Insurance  Policy,  the Refunding
               Bonds and the  Purchase  Agreement,  such  order  being  subject,
               however,  to the  condition,  among others,  that WTU comply with
               such  supplemental  order,  if any, as the  Commission  may enter
               thereunder.  A  copy  of  the  Order  will  be  delivered  to the
               Underwriters.

                    (c)  That  this  Letter  of  Representation  has  been  duly
               executed and delivered by WTU.

                    (d) That the approval of the  Resolution,  the Indenture and
               the Purchase Agreement, the execution and delivery of this Letter
               of  Representation  and the Installment  Agreement and compliance
               with the provisions of such  instruments and  consummation of the
               transactions contemplated hereby and thereby, do not and will not
               conflict with,  violate or result in a breach of any provision of
               or constitute a default (or an event which with notice or passage
               of time, or both,  would constitute a default) on the part of WTU
               under its Restated  Articles of Incorporation  or By-laws,  under
               any indenture, commitment, agreement or other instrument to which
               WTU is a party or by which it is bound or under any existing law,
               rule, regulation,  judgment,  ordinance, order or decree to which
               WTU is  subject;  nor will such  approval,  execution,  delivery,
               compliance or  consummation  result in the creation or imposition
               of any lien,  charge or other security interest or encumbrance of
               any nature  whatsoever  upon any of the property or assets of WTU
               (except the lien, if any, created by the Installment Agreement).

                    (e) That no consent, approval, authorization or order of any
               court or  governmental  agency or body is  required in respect of
               the approval of the  Resolution by WTU, the approval of the terms
               of the  Purchase  Agreement,  the valid  execution,  delivery and
               performance  by WTU of  this  Letter  of  Representation  and the
               Installment   Agreement  or  the   consummation  by  WTU  of  the
               transactions  contemplated by the Purchase Agreement, this Letter
               of  Representation,  the  Installment  Agreement and the Official
               Statement,  except (i) the Order,  (ii) the approving  opinion of
               the  Attorney  General  of the  State  of Texas  relating  to the
               Refunding  Bonds,  (iii) the  registration of the Refunding Bonds
               upon initial  issuance by the  Comptroller of Public  Accounts of
               the  State of  Texas,  and  (iv)  such as may be  required  under
               securities  or Blue Sky laws of any  jurisdiction  in  connection
               with the offering and sale of the Refunding Bonds.

                    (f) That  the  information  with  respect  to it  (including
               Appendix A) and the  Facilities  and the use of the proceeds from
               the  issuance  and sale of the  Refunding  Bonds  included in the
               Indenture,  the  Resolution,   the  Purchase  Agreement  and  the
               Refunding  Bonds  and  the  information  (other  than  under  the
               captions "The Issuer", "The Bonds - Book-Entry Only System", "Tax
               Matters"  and   "Underwriting")   contained  or  incorporated  by
               reference in the Official Statement  (including any amendments or
               supplements thereto) is true and correct in all material respects
               and does not include,  and the Preliminary  Official Statement as
               of its date did not include,  any untrue  statement of a material
               fact or omit to state a material fact  necessary in order to make
               the   statements   therein  not   misleading   in  light  of  the
               circumstances  under which they were made;  that it has  approved
               the  Official  Statement  and  consents to the use thereof by the
               Underwriters  in  connection  with the offering of the  Refunding
               Bonds;  that the  Official  Statement  is deemed final by WTU for
               purposes of Rule  15c2-12  under the  Exchange  Act; and that the
               financial  statements  relating to it included or incorporated by
               reference  in  the  Official  Statement   (including   Appendix A
               thereto)  and  the  Preliminary   Official  Statement  (including
               Appendix A   thereto)  have  been  prepared  in  accordance  with
               generally accepted accounting  principles applied on a consistent
               basis  (except  as  otherwise  disclosed  in the  notes  to  such
               financial  statements) and fairly present its financial condition
               and  the  results  of its  operations  at the  dates  and for the
               respective periods indicated therein.

                    (g)  That  any  document,   certificate   or  other  written
               statement  furnished  by  WTU  to  the  Underwriters  or  McCall,
               Parkhurst  & Horton  L.L.P.,  Bond  Counsel,  or Sidley & Austin,

               statement  of a material  fact or omit to state a  material  fact
               required to be stated  therein or  necessary in order to make the
               statements  therein not misleading in light of the  circumstances
               under which they were made.

                    (h) Except as may be specifically  set forth in the Official
               Statement  and  except  for  the  proceedings   relating  to  the
               approving  opinion of the Attorney  General of the State of Texas
               on the Refunding  Bonds and to the  registration of the Refunding
               Bonds upon initial issuance by the Comptroller of Public Accounts
               of the State of Texas,  there is no action,  suit,  proceeding or
               investigation,  at  law or in  equity,  before  or by any  court,
               governmental  agency or body or arbitrator,  involving WTU or the
               Facilities,  pending or, to the best knowledge of WTU, threatened
               (i) which might  reasonably  be expected  to (x)  materially  and
               adversely affect the condition (financial or otherwise),  results
               of  operations,  business or properties of WTU or (y)  materially
               and adversely  affect the operation,  condition or feasibility of
               the Facilities or (ii) wherein any unfavorable  decision,  ruling
               or finding might  reasonably be expected to (x) adversely  affect
               the transactions  contemplated to be performed by WTU hereby,  by
               the Purchase Agreement,  by the Installment Agreement,  or by the
               Official  Statement  or (y)  adversely  affect  the  validity  or
               enforceability of the Refunding Bonds, the Installment Agreement,
               the Indenture,  the  Resolution,  the Purchase  Agreement or this
               Letter of  Representation or any agreement or instrument to which
               WTU is a party and which is used or  contemplated  for use in the
               consummation of the transactions contemplated hereby or thereby.

                    (i) Arthur Andersen LLP, are independent  public accountants
               with  respect to WTU, as would be required  under the  Securities
               Act and the rules and  regulations  thereunder if the  Securities
               Act and the rules and  regulations  thereunder were applicable to
               the Official Statement.

                    (j)  That  (i) the  Facilities  consist  of  either  land or
               property  of a  character  subject to  depreciation  for  federal
               income tax  purposes and will be used to abate or control air and
               water pollution or contamination by removing, altering, disposing
               or  storing  pollutants,  contaminants,  wastes  or  heat  or  to
               collect,  store or treat  sewage or solid  wastes  prior to final
               disposal  thereof;  (ii) the  Facilities  will not  result  in an
               increase in production or capacity, production efficiencies,  the
               production of a  by-product,  the extension of the useful life of
               any  manufacturing or production  facility or any part thereof at
               the Plant or other property which is not part of the Plant, which
               would  jeopardize  the exclusion of the interest on the Refunding
               Bonds from the gross income of the recipients thereof for federal
               income tax purposes,  and none of the Facilities  would have been
               installed  but for the  purpose of  disposing  of sewage or solid
               waste or controlling  pollution;  and (iii) all other information
               supplied by WTU in connection with the transactions  contemplated
               hereby  and  by  the  Official  Statement  with  respect  to  the
               exclusion  from gross  income for federal  income tax purposes of
               interest on the Refunding Bonds is correct and complete.

                    (k)  That all  required  certificates  that  the  Facilities
               (other than the solid waste disposal  facilities  that require no
               certifications),  as designed,  are in furtherance of the purpose
               of  abating  or  controlling  air or water  pollution  have  been
               obtained from the Texas Natural Resource Conservation  Commission
               ("TNRCC")  or its  predecessor,  and  remain  in full  force  and
               effect.

                    (l) That WTU is eligible  as an issuer to file  registration
               statements  on Form  S-3  under  the  Securities  Act,  and  each
               document filed by it under the Exchange Act and  incorporated (or
               to be incorporated) in the Preliminary  Official Statement or the
               Official  Statement by reference  complied when so filed (or will
               comply when so filed) in all material respects with the act under
               which it was so filed,  and,  during the period  that an Official
               Statement is required to be delivered, no such document hereafter
               so filed will include any 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.

                                                     
                    (m) That there has been no material  adverse change in WTU's
               financial condition or any adverse  development  concerning WTU's
               business and assets which would  reasonably be expected to result
               in  a  material  adverse  change  in  its  prospective  financial
               condition  or  results  of  operations  from  that  shown  in the
               Official Statement.

                    (n) That no event of default or event which,  with notice or
               passage of time, or both, would constitute an event of default or
               a default  under any  agreement or  instrument  to which WTU is a
               party or by  which  it is or may be bound or to which  any of its
               property  or  assets  is  or  may  be  subject  and  which  would
               materially and adversely affect the transactions  contemplated by
               the Installment Agreement,  the Official Statement or this Letter
               of Representation has occurred and is continuing.

                    (o) WTU is not  currently  in default in the  payment of the
               principal  of, or  interest  on, any  security  or other  legally
               authorized obligation issued by it.

     3.  Representations  by PSO. PSO makes the  following  representations  and
warranties, all of which shall survive the termination of the Purchase Agreement
and the sale and delivery of the Refunding Bonds to the Underwriters.

                    (a)  That  it  is  a  corporation  duly  organized,  validly
               existing  and in good  standing  under  the laws of the  State of
               Oklahoma and is duly  qualified as a foreign  corporation  and in
               good  standing  under the laws of the  State of Texas,  with full
               corporate  power and  authority  to engage  in the  business  and
               activities conducted by it as described in the Official Statement
               and,  subject to the opinion of the Attorney General of the State
               of Texas  approving the Refunding  Bonds and the  registration of
               the  Refunding  Bonds upon initial  issue by the  Comptroller  of
               Public  Accounts of the State of Texas,  the receipt of which are
               expressly  made  a  condition  to  PSO's  obligations  under  the
               Installment  Agreement,  has full power and  authority to execute
               and deliver and to carry out and  perform its  obligations  under
               this Letter of Representation and the Installment Agreement.

                    (b) That it has duly  approved the forms of the  Resolution,
               the  Indenture  and  the  Purchase  Agreement.   The  Installment
               Agreement has been duly authorized, executed and delivered by PSO
               and is a legal,  valid and binding  obligation of PSO enforceable
               in accordance  with its terms,  subject,  as to  enforcement,  to
               bankruptcy,  insolvency,  reorganization,   moratorium  or  other
               similar laws relating to or affecting creditors' rights generally
               and to the effect of general  principles of equity (regardless of
               whether enforceability is considered in a proceeding in equity or
               at  law).  PSO has  duly  authorized  the  taking  of all  action
               necessary  to  carry  out and  give  effect  to the  transactions
               contemplated to be performed by it by the Official Statement, the
               Installment Agreement,  the Purchase Agreement and this Letter of
               Representation.  PSO expects that the  Commission  will issue the
               Order  under  the  1935  Act  on or  prior  to the  Closing  Date
               authorizing PSO's (and WTU's and CPL's)  obligations with respect
               to this Letter of Representation,  the Installment Agreement, the
               Municipal  Bond  Insurance  Policy,  the Refunding  Bonds and the
               Purchase  Agreement,  such order being subject,  however,  to the
               condition,  among others,  that PSO comply with such supplemental
               order, if any, as the Commission may enter thereunder.  A copy of
               the Order will be delivered to the Underwriters.

                    (c)  That  this  Letter  of  Representation  has  been  duly
               executed and delivered by PSO.

                    (d) That the approval of the  Resolution,  the Indenture and
               the Purchase Agreement, the execution and delivery of this Letter
               of  Representation  and the Installment  Agreement and compliance
               with the provisions of such  instruments and  consummation of the
               transactions contemplated hereby and thereby, do not and will not
               conflict with,  violate or result in a breach of any provision of
               or constitute a default (or an event which with notice or passage
               of time, or both,  would constitute a default) on the part of PSO
               under its Amended and Restated  Certificate of  Incorporation  or
               By-laws,  under any  indenture,  commitment,  agreement  or other
               instrument  to  which  PSO is a party  or by which it is bound or
               under any existing law, rule,  regulation,  judgment,  ordinance,
               order or decree to which PSO is subject;  nor will such approval,
               execution,  delivery,  compliance or  consummation  result in the
               creation  or  imposition  of any lien,  charge or other  security
               interest or encumbrance of any nature  whatsoever upon any of the
               property or assets of PSO (except  the lien,  if any,  created by
               the Installment Agreement).

                    (e) That no consent, approval, authorization or order of any
               court or  governmental  agency or body is  required in respect of
               the approval of the  Resolution by PSO, the approval of the terms
               of the  Purchase  Agreement,  the valid  execution,  delivery and
               performance  by PSO of  this  Letter  of  Representation  and the

               transactions  contemplated by the Purchase Agreement, this Letter
               of  Representation,  the  Installment  Agreement and the Official
               Statement,  except (i) the Order,  (ii) the approving  opinion of
               the  Attorney  General  of the  State  of Texas  relating  to the

               upon initial  issuance by the  Comptroller of Public  Accounts of
               the State of Texas,  (iv) the order of the  Oklahoma  Corporation
               Commission  and (v) such as may be required  under  securities or
               Blue Sky laws of any jurisdiction in connection with the offering
               and sale of the Refunding Bonds.

                    (f) That  the  information  with  respect  to it  (including
               Appendix B) and the  Facilities  and the use of the proceeds from
               the  issuance  and sale of the  Refunding  Bonds  included in the
               Indenture,  the  Resolution,   the  Purchase  Agreement  and  the
               Refunding  Bonds  and  the  information  (other  than  under  the
               captions "The Issuer", "The Bonds - Book-Entry Only System", "Tax
               Matters"  and   "Underwriting")   contained  or  incorporated  by
               reference in the Official Statement  (including any amendments or
               supplements thereto) is true and correct in all material respects
               and does not include,  and the Preliminary  Official Statement as
               of its date did not include,  any untrue  statement of a material
               fact or omit to state a material fact  necessary in order to make
               the   statements   therein  not   misleading   in  light  of  the
               circumstances  under which they were made;  that it has  approved
               the  Official  Statement  and  consents to the use thereof by the
               Underwriters  in  connection  with the offering of the  Refunding
               Bonds;  that the  Official  Statement  is deemed final by PSO for
               purposes of Rule  15c2-12  under the  Exchange  Act; and that the
               financial  statements  relating to it included or incorporated by
               reference  in  the  Official  Statement   (including   Appendix B
               thereto)  and  the  Preliminary   Official  Statement  (including
               Appendix B   thereto)  have  been  prepared  in  accordance  with
               generally accepted accounting  principles applied on a consistent

               financial  statements) and fairly present its financial condition
               and  the  results  of its  operations  at the  dates  and for the
               respective periods indicated therein.

                    (g)  That  any  document,   certificate   or  other  written
               statement  furnished  by  PSO  to  the  Underwriters  or  McCall,

               statements  therein not misleading in light of the  circumstances
               under which they were made.

                    (h) Except as may be specifically  set forth in the Official
               Statement  and  except  for  the  proceedings   relating  to  the
               approving  opinion of the Attorney  General of the State of Texas
               on the Refunding  Bonds and to the  registration of the Refunding
               Bonds upon initial issuance by the Comptroller of Public Accounts
               of the State of Texas,  there is no action,  suit,  proceeding or
               investigation,  at  law or in  equity,  before  or by any  court,
               governmental  agency or body or arbitrator,  involving PSO or the
               Facilities,  pending or, to the best knowledge of PSO, threatened
               (i) which might  reasonably  be expected  to (x)  materially  and
               adversely affect the condition (financial or otherwise),  results
               of  operations,  business or properties of PSO or (y)  materially
               and adversely  affect the operation,  condition or feasibility of
               the Facilities or (ii) wherein any unfavorable  decision,  ruling
               or finding might  reasonably be expected to (x) adversely  affect
               the transactions  contemplated to be performed by PSO hereby,  by
               the Purchase  Agreement,  by the Installment  Agreement or by the
               Official  Statement  or (y)  adversely  affect  the  validity  or
               enforceability of the Refunding Bonds, the Installment Agreement,
               the Indenture,  the  Resolution,  the Purchase  Agreement or this
               Letter of  Representation or any agreement or instrument to which
               PSO is a party and which is used or  contemplated  for use in the
               consummation of the transactions contemplated hereby or thereby.

                    (i) Arthur Andersen LLP, are independent  public accountants
               with  respect to PSO, as would be required  under the  Securities
               Act and the rules and  regulations  thereunder if the  Securities
               Act and the rules and  regulations  thereunder were applicable to
               the Official Statement.

                    (j)  That  (i) the  Facilities  consist  of  either  land or
               property  of a  character  subject to  depreciation  for  federal
               income tax  purposes and will be used to abate or control air and
               water pollution or contamination by removing, altering, disposing
               or  storing  pollutants,  contaminants,  wastes  or  heat  or  to
               collect,  store or treat  sewage or solid  wastes  prior to final
               disposal  thereof;  (ii) the  Facilities  will not  result  in an
               increase in production or capacity, production efficiencies,  the
               production of a  by-product,  the extension of the useful life of
               any  manufacturing or production  facility or any part thereof at
               the Plant or other property which is not part of the Plant, which
               would  jeopardize  the exclusion of the interest on the Refunding
               Bonds from the gross income of the recipients thereof for federal
               income tax purposes,  and none of the Facilities  would have been
               installed  but for the  purpose of  disposing  of sewage or solid
               waste or controlling  pollution;  and (iii) all other information
               supplied by PSO in connection with the transactions  contemplated
               hereby  and  by  the  Official  Statement  with  respect  to  the
               exclusion  from gross  income for federal  income tax purposes of
               interest on the Refunding Bonds is correct and complete.

                    (k)  That all  required  certificates  that  the  Facilities
               (other than the solid waste disposal  facilities  that require no
               certifications),  as designed,  are in furtherance of the purpose
               of  abating  or  controlling  air or water  pollution  have  been
               obtained  from the TNRCC or its  predecessor,  and remain in full
               force and effect.

                    (l) That PSO is eligible  as an issuer to file  registration
               statements  on Form  S-3  under  the  Securities  Act,  and  each
               document filed by it under the Exchange Act and  incorporated (or
               to be incorporated) in the Preliminary  Official Statement or the
               Official  Statement by reference  complied when so filed (or will
               comply when so filed) in all material respects with the act under
               which it was so filed,  and,  during the period  that an Official
               Statement is required to be delivered, no such document hereafter
               so filed will include any 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.

                    (m) That there has been no material  adverse change in PSO's
               financial condition or any adverse  development  concerning PSO's
               business and assets which would  reasonably be expected to result
               in  a  material  adverse  change  in  its  prospective  financial
               condition  or  results  of  operations  from  that  shown  in the
               Official Statement.

                    (n) That no event of default or event which,  with notice or
               passage of time, or both, would constitute an event of default or
               a default  under any  agreement or  instrument  to which PSO is a
               party or by  which  it is or may be bound or to which  any of its
               property  or  assets  is  or  may  be  subject  and  which  would
               materially and adversely affect the transactions  contemplated by
               the Installment Agreement,  the Official Statement or this Letter
               of Representation has occurred and is continuing.

                    (o) PSO is not  currently  in default in the  payment of the
               principal  of, or  interest  on, any  security  or other  legally
               authorized obligation issued by it.

                  4.       Representations by CPL.  CPL makes the following
representations and warranties, all of which shall survive the
termination of the Purchase Agreement and the sale and delivery
of the Refunding Bonds to the Underwriters.

               Agreement has been duly authorized, executed and delivered by CPL
               and is a legal,  valid and binding  obligation of CPL enforceable
               in accordance  with its terms,  subject,  as to  enforcement,  to
               bankruptcy,  insolvency,  reorganization,   moratorium  or  other
               similar laws relating to or affecting creditors' rights generally
               and to the effect of general  principles of equity (regardless of
               whether enforceability is considered in a proceeding in equity or
               at  law).  CPL has  duly  authorized  the  taking  of all  action
               necessary  to  carry  out and  give  effect  to the  transactions
               contemplated to be performed by it by the Official Statement, the

               Purchase  Agreement,  such order being subject,  however,  to the
               condition,  among others,  that CPL comply with such supplemental
               order, if any, as the Commission may enter thereunder.  A copy of
               the Order will be delivered to the Underwriters.

                    (c)  That  this  Letter  of  Representation  has  been  duly
               executed and delivered by CPL.

               the Purchase Agreement, the execution and delivery of this Letter
               of  Representation  and the Installment  Agreement and compliance
               with the provisions of such  instruments and  consummation of the
               transactions contemplated hereby and thereby, do not and will not
               conflict with,  violate or result in a breach of any provision of

               any indenture, commitment, agreement or other instrument to which
               CPL is a party or by which it is bound or under any existing law,
               rule, regulation,  judgment,  ordinance, order or decree to which
               CPL is  subject;  nor will such  approval,  execution,  delivery,
               compliance or  consummation  result in the creation or imposition
               of any lien,  charge or other security interest or encumbrance of
               any nature  whatsoever  upon any of the property or assets of CPL
               (except the lien, if any, created by the Installment Agreement).

               the  Attorney  General  of the  State  of Texas  relating  to the
               Refunding  Bonds,  (iii) the  registration of the Refunding Bonds
               upon initial  issuance by the  Comptroller of Public  Accounts of

               securities  or Blue Sky laws of any  jurisdiction  in  connection
               with the offering and sale of the Refunding Bonds.

               captions "The Issuer", "The Bonds - Book-Entry Only System", "Tax
               Matters"  and   "Underwriting")   contained  or  incorporated  by
               reference in the Official Statement  (including any amendments or
               supplements thereto) is true and correct in all material respects
               and does not include,  and the Preliminary  Official Statement as
               of its date did not include,  any untrue  statement of a material
               fact or omit to state a material fact  necessary in order to make
               the   statements   therein  not   misleading   in  light  of  the
               circumstances  under which they were made;  that it has  approved
               the  Official  Statement  and  consents to the use thereof by the
               Underwriters  in  connection  with the offering of the  Refunding
               Bonds;  that the  Official  Statement  is deemed final by CPL for
               purposes of Rule  15c2-12  under the  Exchange  Act; and that the
               financial  statements  relating to it included or incorporated by
               reference  in  the  Official  Statement   (including   Appendix C
               thereto)  and  the  Preliminary   Official  Statement  (including
               Appendix C   thereto)  have  been  prepared  in  accordance  with
               generally accepted accounting  principles applied on a consistent
               basis  (except  as  otherwise  disclosed  in the  notes  to  such
               financial  statements) and fairly present its financial condition
               and  the  results  of its  operations  at the  dates  and for the
               respective periods indicated therein.

                    (g)  That  any  document,   certificate   or  other  written
               statement  furnished  by  CPL  to  the  Underwriters  or  McCall,
               Parkhurst  & Horton  L.L.P.,  Bond  Counsel,  or Sidley & Austin,
               counsel to the  Underwriters,  relating to CPL, the Facilities or
               the Refunding Bonds is true and correct in all material  respects
               and does not or will not, as the case may be,  include any untrue
               statement  of a material  fact or omit to state a  material  fact
               required to be stated  therein or  necessary in order to make the
               statements  therein not misleading in light of the  circumstances
               under which they were made.

                    (h) Except as may be specifically  set forth in the Official
               Statement  and  except  for  the  proceedings   relating  to  the
               approving  opinion of the Attorney  General of the State of Texas
               on the Refunding  Bonds and to the  registration of the Refunding
               Bonds upon initial issuance by the Comptroller of Public Accounts
               of the State of Texas,  there is no action,  suit,  proceeding or
               investigation,  at  law or in  equity,  before  or by any  court,
               governmental  agency or body or arbitrator,  involving CPL or the
               Facilities,  pending or, to the best knowledge of CPL, threatened
               (i) which might  reasonably  be expected  to (x)  materially  and
               adversely affect the condition (financial or otherwise),  results
               of  operations,  business or properties of CPL or (y)  materially
               and adversely  affect the operation,  condition or feasibility of
               the Facilities or (ii) wherein any unfavorable  decision,  ruling
               or finding might  reasonably be expected to (x) adversely  affect
               the transactions  contemplated to be performed by CPL hereby,  by
               the Purchase  Agreement,  by the Installment  Agreement or by the
               Official  Statement  or (y)  adversely  affect  the  validity  or
               enforceability of the Refunding Bonds, the Installment Agreement,
               the Indenture,  the  Resolution,  the Purchase  Agreement or this
               Letter of  Representation or any agreement or instrument to which
               CPL is a party and which is used or  contemplated  for use in the
               consummation of the transactions contemplated hereby or thereby.

                    (i) Arthur Andersen LLP, are independent  public accountants
               with  respect to CPL, as would be required  under the  Securities
               Act and the rules and  regulations  thereunder if the  Securities
               Act and the rules and  regulations  thereunder were applicable to
               the Official Statement.

                    (j)  That  (i) the  Facilities  consist  of  either  land or
               property  of a  character  subject to  depreciation  for  federal
               income tax  purposes and will be used to abate or control air and
               water pollution or contamination by removing, altering, disposing
               or  storing  pollutants,  contaminants,  wastes  or  heat  or  to
               collect,  store or treat  sewage or solid  wastes  prior to final
               disposal  thereof;  (ii) the  Facilities  will not  result  in an
               increase in production or capacity, production efficiencies,  the
               production of a  by-product,  the extension of the useful life of
               any  manufacturing or production  facility or any part thereof at
               the Plant or other property which is not part of the Plant, which
               would  jeopardize  the exclusion of the interest on the Refunding
               Bonds from the gross income of the recipients thereof for federal
               income tax purposes,  and none of the Facilities  would have been
               installed  but for the  purpose of  disposing  of sewage or solid
               waste or controlling  pollution;  and (iii) all other information
               supplied by CPL in connection with the transactions  contemplated
               hereby  and  by  the  Official  Statement  with  respect  to  the
               exclusion  from gross  income for federal  income tax purposes of
               interest on the Refunding Bonds is correct and complete.

                    (k)  That all  required  certificates  that  the  Facilities
               (other than the solid waste disposal  facilities  that require no
               certifications),  as designed,  are in furtherance of the purpose
               of  abating  or  controlling  air or water  pollution  have  been
               obtained  from the TNRCC or its  predecessor,  and remain in full
               force and effect.

                    (l) That CPL is eligible  as an issuer to file  registration
               statements  on Form  S-3  under  the  Securities  Act,  and  each
               document filed by it under the Exchange Act and  incorporated (or
               to be incorporated) in the Preliminary  Official Statement or the
               Official  Statement by reference  complied when so filed (or will
               comply when so filed) in all material respects with the act under
               which it was so filed,  and,  during the period  that an Official
               Statement is required to be delivered, no such document hereafter
               so filed will include any 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.

                                  
                    (m) That there has been no material  adverse change in CPL's
               financial condition or any adverse  development  concerning CPL's
               business and assets which would  reasonably be expected to result
               in  a  material  adverse  change  in  its  prospective  financial
               condition  or  results  of  operations  from  that  shown  in the
               Official Statement.

                    (n) That no event of default or event which,  with notice or
               passage of time, or both, would constitute an event of default or
               a default  under any  agreement or  instrument  to which CPL is a
               party or by  which  it is or may be bound or to which  any of its
               property  or  assets  is  or  may  be  subject  and  which  would
               materially and adversely affect the transactions  contemplated by
               the Installment Agreement,  the Official Statement or this Letter
               of Representation has occurred and is continuing.

                    (o) CPL is not  currently  in default in the  payment of the
               principal  of, or  interest  on, any  security  or other  legally
               authorized obligation issued by it.

                  5.       Covenants of the Companies.  Each of the Companies
will:

                    (a) Notify the  Underwriters of any material  adverse change
               in its  business,  properties  or financial  condition  occurring
               before  Closing or within  three  months  thereafter  which would
               require revision of the information in the Official  Statement in
               order to make the  representations  set forth in  Sections  2(f),
               3(f) or 4(f) hereof, as the case may be, true and correct.

                    (b) Refrain from taking any action,  or from  permitting any
               action,  with  regard  to which it may  exercise  control,  to be
               taken, that (i) would in any way cause the proceeds from the sale
               of the  Refunding  Bonds to be applied in a manner  other than as
               provided  in  the  Resolution,  the  Installment  Agreement,  the
               Indenture  and  discussed in the Official  Statement,  (ii) would
               result in the loss of the exclusion from gross income for federal
               income tax purposes of interest on the Refunding  Bonds, or (iii)
               it has reason to believe will adversely  jeopardize the continued
               validity and effectiveness of such exemption.

                    (c)  Deliver  to the  Underwriters  upon  request  copies of
               documents of such  Company  incorporated  by  reference  into the
               Official Statement and all documents to which Section 5(d) hereof
               refers at such times and in such  quantities  as are necessary to
               enable the Underwriters to satisfy requests for such information,
               and enable the Underwriters to make such documents  available for
               inspection, as described in the Official Statement.

                    (d)  During  the period  commencing  on the date  hereof and
               ending upon completion of the distribution of the Refunding Bonds
               (but  in no  event  later  than  90 days  after  the  date of the
               Closing),  promptly after filing any document with the Commission
               pursuant to Section 13, 14 or 15(d) of the Exchange Act,  furnish
               a copy thereof to the Underwriters and the Issuer.

                    (e) Comply with and perform its obligations set forth in its
               Rule 15c2-12 Undertakings  attached hereto as Exhibit 1, which is
               hereby incorporated by reference herein.

                    (f) Before amending or supplementing the Official Statement,
               furnish  to the  Underwriters  two  copies  and to the Issuer two
               copies of each proposed amendment or supplement.  No amendment or
               supplement  to  the  Official  Statement  will  contain  material
               information  different  from that contained in the Final Official
               Statement which is reasonably  unsatisfactory to the Underwriters
               or the Issuer.

                    (g) During such period as the Underwriters  believe delivery
               of the Official Statement is necessary or desirable in connection
               with  sales  of the  Refunding  Bonds  by the  Underwriters  or a
               dealer,  if any event  shall occur as a result of which it may be
               necessary to amend or supplement the Official  Statement in order
               to make the statement therein,  in the light of the circumstances
               when the Official  Statement  is  delivered  to a purchaser,  not
               misleading, immediately notify the Underwriters and the Issuer of
               such event and  cooperate at the request of the  Underwriters  in
               the  preparation  of  amendments or  supplements  to the Official
               Statement which in the judgment of the Underwriters are necessary
               so that the statements in the Official Statement as so amended or
               supplemented  will not,  in light of the  circumstances  when the
               Official Statement is delivered to a purchaser, be misleading.

     6.  Indemnification;  Contribution.  (a) Each of the  Companies  agrees  to
indemnify  and hold  harmless the Issuer,  its  officials,  directors,  members,
officers,  employees and agents and each of the  Underwriters,  their respective
officers, directors,  officials, employees and each person, if any, who controls
any  Underwriter  within the  meaning of  Section  15 of the  Securities  Act or
Section 20 of the Exchange Act  (collectively,  "Indemnified  Parties") from and
against  any and all  losses,  claims,  damages  or  liabilities  to which  such
Indemnified  Party may become subject under the Securities Act, the Exchange Act
or the common law or otherwise, and to reimburse each such Indemnified Party for
any  reasonable  legal or other  expenses  (including  reasonable  counsel fees)
incurred by it or them in  connection  with  defending  against any such losses,
claims,  damages  or  liabilities,  arising  out of or in  connection  with  the
offering and sale of the Refunding  Bonds (i) on the ground that the Preliminary
Official  Statement or the Final Official  Statement (except with respect to the
Issuer for the information relating to the Issuer under the caption "The Issuer"
and with  respect to any such  Underwriter  for  information  under the  caption
"Underwriting"  and any  information  furnished  in writing by such  Underwriter
specifically for use therein) includes any untrue statement or an alleged untrue
statement  of material  fact or any  omission or an alleged  omission to state a
material fact necessary in order to make the  statements  therein not misleading
in light of the  circumstances  under which they were made,  or (ii)  arising by
virtue of the failure to register the Refunding  Bonds under the  Securities Act
or to qualify the Indenture under the Trust Act. The obligation of the Companies
to  indemnify  and hold  harmless  the  Indemnified  Parties  shall be (i) borne
entirely  by each  Company  with  respect  to the  appendix  to the  Preliminary
Official  Statement or Final  Official  Statement  which  relates to it and (ii)
otherwise  shall be borne  by each  Company  in  accordance  with its  Ownership
Percentage (as defined in the Indenture).

                    (b) By  its  acceptance  hereof,  each  of the  Underwriters
               agrees  severally  and not jointly to indemnify and hold harmless
               the Issuer,  its  officers,  directors,  employees and agents and
               each of the Companies,  their respective officers,  directors and
               employees,  and each person,  if any,  who controls  such Company
               within  the  meaning  of  Section  15 of  the  Securities  Act or
               Section 20  of  the  Exchange  Act  (collectively,   "Indemnified
               Parties"),  from and against any and all losses,  claims, damages
               or liabilities to which such Indemnified Party may become subject
               under the  Securities  Act, the Exchange Act or the common law or
               otherwise,  and to reimburse each such Indemnified  Party for any
               reasonable legal or other expenses (including  reasonable counsel
               fees) incurred by it or them in connection with defending against
               any such losses, claims,  damages or liabilities,  arising out of
               or in  connection  with the  offering  and sale of the  Refunding
               Bonds on the  grounds  that the  information  under  the  caption
               "Underwriting"   furnished   by  such   Underwriter   in  writing
               specifically for use in the Preliminary Official Statement or the
               Final Official Statement includes any untrue statement or alleged
               untrue  statement of a material fact or an omission or an alleged
               omission to state a material fact  necessary in order to make the
               statements  therein not misleading in light of the  circumstances
               under which they were made.

                    (c) Promptly after the commencement of any action against an
               Indemnified  Party  hereunder in respect of which indemnity is to
               be  sought   against  the  Companies  (or  any  Company)  or  any
               Underwriter,  as the case may be (the "Indemnifying Party"), such
               Indemnified  Party will notify the Indemnifying  Party in writing
               of such action and the  Indemnifying  Party may  participate  in,
               and,  to the  extent  that it may  wish,  jointly  with any other
               Indemnifying  Party  similarly   notified,   assume  the  defense
               thereof,  including the  employment of counsel and the payment of
               all  expenses;  but the  omission  so to notify the  Indemnifying
               Party will not relieve the Indemnifying  Party from any liability
               which  it  may  have  to any  Indemnified  Party  otherwise  than
               hereunder.  The  Indemnifying  Party  shall not be liable for any
               settlement of any such action effected  without its consent,  but
               if settled with the consent of the Indemnifying Party or if there
               is a final  judgment for the  plaintiff  in any such action,  the
               Indemnifying   Party  will   indemnify   and  hold  harmless  any
               Indemnified  Party  from and  against  any loss or  liability  by
               reason of such settlement or judgment.  The indemnity  agreements
               contained  herein  shall  include   reimbursement   for  expenses
               reasonably  incurred by an Indemnified Party in investigating the
               claim and in defending it if the  Indemnifying  Party declines to
               assume the defense and shall survive  termination of the Purchase
               Agreement,  this Letter of Representation and the delivery of the
               Refunding Bonds.

                    (d) If the indemnification provided for in this Section 6 is
               unavailable  to or  insufficient  to hold harmless an Indemnified
               Party  under  Subsection  (a)  above in  respect  of any  losses,
               claims,  damages or liabilities  (or actions in respect  thereof)
               referred to therein,  then each of the Companies shall contribute
               to the  amount  paid or payable  by such  Indemnified  Party as a
               result of such losses, claims, damages or liabilities (or actions
               in respect  thereof)  in such  proportion  as is  appropriate  to
               reflect the relative  fault of the  Companies (or any Company) on
               the one hand and the Indemnified Party on the other in connection
               with the  statements or omissions or other matters which resulted
               in such losses,  claims,  damages and  liabilities (or actions in
               respect  thereof),  as  well  as  any  other  relevant  equitable
               considerations.  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 any
               of the Companies on the one hand or the Indemnified  Party on the
               other and each such party's relative intent, knowledge, access to
               information  and  opportunity  to correct or prevent  such untrue
               statement or omission. Each of the Companies and the Underwriters
               agree  that it would not be just and  equitable  if  contribution
               pursuant to this  Subsection  (d) were  determined  solely by pro
               rata  allocation or by any other method of allocation  which does
               not take  account of the  equitable  considerations  referred  to

                          INTRODUCTION

     This Official Statement is provided to furnish information
regarding the issuance by Red River Authority of Texas, a
governmental agency and body politic and corporate of the State of
Texas (the "Issuer"), of its Pollution Control Revenue Refunding
Bonds (West Texas Utilities Company, Public Service Company of
Oklahoma and Central Power and Light Company Oklaunion Project)
Series 1996 (the "Bonds") in the aggregate principal amount of
$63,300,000.

     The issuance and sale of the Bonds has been authorized by a
Resolution adopted by the Issuer on July 17, 1996 (the
"Resolution").  The Bonds will be issued pursuant to an Indenture
of Trust to be dated as of July 1, 1996 (the "Indenture") between
the Issuer and The Bank of New York, as trustee (the "Trustee"). 

     The proceeds of the Bonds will be used to refund $63,300,000
of the Issuer's outstanding Adjustable Rate Pollution Control
Revenue Refunding Bonds (West Texas Utilities Company, Public
Service Company of Oklahoma and Central Power and Light Company
Oklaunion Project) Series 1984 (the "Prior Bonds").  The Prior
Bonds were originally issued to acquire, construct and improve
certain air and water pollution control and solid waste disposal
facilities (the "Facilities") at the Oklaunion Electric Generating
Plant near Vernon, Texas (the "Plant") in which West Texas
Utilities Company, a Texas corporation ("WTU"), Public Service
Company of Oklahoma, an Oklahoma corporation ("PSO"), and Central
Power and Light Company, a Texas corporation ("CPL") (collectively,
the "Companies" or individually, a "Company"), own 54.7%, 15.6% and
7.8% undivided interests, respectively.  The respective undivided
ownership percentages of each of the Companies (the "Ownership
Percentage") of the portion of the Facilities financed from the
proceeds of the Prior Bonds is 70% for WTU, 20% for PSO and 10% for
CPL.

     Pursuant to an Installment Payment Agreement dated as of
July 1, 1996 (the "Agreement") between the Issuer, the Companies
and Central and South West Services, Inc., as agent for the
Companies (the "Agent"), the Companies will be obligated to make
payments at such times and in such amounts as shall be required to
pay, when due, the principal of, premium, if any, interest on, and
Purchase Price for, the Bonds.  The payments will be made directly
to the Trustee.  Neither the Facilities nor the Plant constitute
security for the Bonds, which will be secured only by the
assignment and pledge of the Agreement, the moneys deposited or
required to be deposited under the Indenture (other than moneys
deposited to the Rebate Fund and the Bond Purchase Fund), and each
Company's absolute unconditional and several obligation to make
payments thereunder pro rata according to each such Company's
Ownership Percentage.

     There follows in this Official Statement brief descriptions of
the Issuer, the Facilities, the Use of Proceeds, the Bonds, the
Agreement and the Indenture.  The descriptions herein of the
Agreement and the Indenture do not purport to be complete and are
qualified in their entirety by reference to such documents, and the

thereto included in the Indenture.  See "MISCELLANEOUS" herein for

respectively, including certain financial statements and other
information incorporated therein by reference.  Terms not defined
herein have the meanings set forth in the Agreement, the Indenture,

                           THE ISSUER

     Red River Authority of Texas is a governmental agency and body
politic and corporate of the State of Texas, created as a
conservation and reclamation district pursuant to Article XVI,
Section 59, of the Constitution of Texas and by Chapter 279, Acts
of the Regular Session of the 56th Texas Legislature, 1959 (Article
8280-228, Vernon's Annotated Texas Civil Statutes) (the "Act"). 
The principal office of the Issuer is in Wichita Falls, Texas.  The
jurisdiction of the Issuer is comprised of most of the territory
lying within the watershed of the Red River and its tributary
streams which is located within the State of Texas.

                         THE FACILITIES

     The Facilities consist of the Companies' portion of the air
and water pollution control and solid waste disposal facilities
acquired, constructed and improved as a part of the total
environmental control program at the Plant.  The Plant is a coal-

operation in December 1986.

     The Facilities consist primarily of an electrostatic
precipitator, ash handling system, sulfur dioxide removal system,
sludge handling and treating system, dust control system, water
handling equipment and solid waste disposal landfill for the Plant. 
The Texas Air Control Board and the Texas Department of Water
Resources (predecessors to the Texas Natural Resources Conservation
Commission) have certified that the Facilities (other than certain
solid waste disposal facilities for which no certification is
required), as built and designed, are in furtherance of the purpose
of abating or controlling atmospheric pollutants or contaminants or
water pollution, as the case may be.

                         USE OF PROCEEDS

     The Bonds are being issued by the Issuer for the purpose of

Bank of New York (successor to RepublicBank Dallas, National
Association) ("The Bank of New York") pursuant to an Indenture of
Trust dated as of September 15, 1984, between the Issuer and The
Bank of New York.  The Companies will provide any additional funds
required to redeem all of the Prior Bonds from either internally
generated funds or short-term borrowings.

                            THE BONDS

     The Bonds will be issuable only as fully registered bonds
without coupons in denominations of $5,000 or any integral multiple
thereof.  Bonds may be transferred or exchanged without cost,

will mature on June 1, 2020 and will bear interest at the rate of
6% per annum until maturity, unless converted in lieu of optional
redemption as described under the caption "Redemption-Mandatory
Tender and Conversion in Lieu of Optional Redemption."  Principal
of and premium, if any, on the Bonds will be payable at the
corporate trust office of the Trustee in New York, New York. 
Interest on the Bonds will be payable semi-annually on June 1 and
December 1 of each year, commencing December 1, 1996, and will be
paid by check mailed on the Interest Payment Date to the registered
owners thereof of record as of the 15th day (whether or not a
Business Day) of the calendar month immediately preceding an
Interest Payment Date, provided that any Registered Owner of
$1,000,000 or more in aggregate principal amount of the Bonds may,
upon written request given to the Paying Agent at least five
Business Days prior to an Interest Payment Date designating an
account in a domestic bank, be paid by wire transfer of immediately
available funds.  Each such payment date is hereinafter referred to
as an "Interest Payment Date."  

     The Bank of New York, the Trustee under the Indenture, has
been appointed as Paying Agent (the "Paying Agent") under the
Indenture.  The Principal Office of the Paying Agent is located at
101 Barclay Street, New York, New York 10286.

Limited Obligations of the Issuer

     The Bonds will be limited obligations of the Issuer, payable
solely from, and secured equally and ratably by, a first lien on
and pledge of all the right, title and interest of the Issuer in
and to the Agreement, including all moneys payable thereunder
(except for certain rights of the Issuer relating to the payment of
expenses and indemnification).  Each Company is absolutely and
unconditionally obligated under the Agreement to pay to the
Trustee, for the account of the Issuer, an amount sufficient to
pay, or provide for the payment of, its Ownership Percentage of the
principal of, premium, if any, and interest on the Bonds when due
(whether upon maturity, redemption or otherwise), and to pay
certain other charges.   Neither the credit nor the taxing power of
the State of Texas, the Issuer or any other political subdivision
of the State of Texas is pledged for the payment of the principal
of, premium, if any, or interest on the Bonds; the Bonds shall not
be deemed a general obligation of the State of Texas, the Issuer or
any other political subdivision of the state of Texas; and none of
the State of Texas, the Issuer or any other political subdivision
of the State of Texas shall be liable for the payment of the
principal of, premium, if any, or interest on the Bonds, except
from those revenues to be derived by the Issuer pursuant to the
Agreement and pledged to such payment.  No holder of a Bond shall
have the right to demand payment from moneys derived by taxation or
any revenues of the Issuer, except the funds pledged to the payment
of the Bonds.

     Notwithstanding its authorization of the Bonds and its
approval of the distribution of this Official Statement, the Issuer
does not endorse, or in any manner guarantee or promise, directly
or indirectly, to pay any obligations on the Bonds from any source
of funds other than as described herein, nor does the Issuer
guarantee, warrant or endorse the creditworthiness or credit
standing of the Companies or in any manner guarantee, warrant or
endorse the investment quality or value of the Bonds.

Redemption

     The Bonds are subject to redemption prior to maturity as
follows:

     Optional Redemption

     The Bonds are subject to redemption prior to maturity at the
option of the Issuer, upon written direction of the Agent delivered
to the Trustee, in whole or in part on June 1, 2006 and on any
Business Day thereafter at the following redemption prices
(expressed as percentages of the principal amount of the Bonds
called for redemption) plus accrued interest to the date fixed for
redemption:
 
     Redemption Date (dates inclusive)            Redemption Price

     June 1, 2006 through May 31, 2007            102%
     June 1, 2007 through May 31, 2008            101%
     June 1, 2008 and thereafter                  100%
 
     Extraordinary Optional Redemption

     The Bonds are subject to redemption in whole on the next
available Interest Payment Date for which notice of redemption can
be given, at a redemption price equal to the aggregate principal
amount of the Bonds Outstanding plus accrued interest thereon to
the redemption date, without premium, upon receipt by the Trustee
of a written notice from the Agent stating that any of the
following events has occurred within the preceding 270 days and
that it intends to exercise its option to effect the redemption of
the Bonds as a whole:

          (a)  in the reasonable judgment of the Agent,
unreasonable burdens or excessive liabilities shall have been
imposed upon the Issuer or the Companies with respect to the
Facilities or the Plant, including, without limitation, (i) the
imposition of any income or other taxes not imposed on July 1, 1996
or (ii) the imposition of any ad valorem property or other taxes
(other than ad valorem property or other taxes imposed on July 1,
1996 upon similarly assessed property within the same taxing
jurisdiction);

          (b)  the Facilities or the Plant shall have been damaged
or destroyed to such extent that, in the opinion of the Agent, (i)
within a period of six consecutive months following such damage or
destruction, it is not practicable or desirable to rebuild, repair
or restore the same, (ii) the Companies will be thereby prevented
from carrying on their normal operations of the Facilities or the
Plant for a period of six or more consecutive months or (iii) the
cost of restoration would exceed by $1,500,000 or more the net
proceeds of insurance thereon;

          (c)  title to, or temporary use of, all or substantially
all of the Facilities or the Plant shall have been taken under the
exercise of the power of eminent domain;

          (d)  changes in the economic availability of materials,
labor, services, supplies (including fuel), equipment or other
property, facilities or things necessary for the operation of the
Facilities or the Plant shall have occurred, or technological,
regulatory or other changes shall have occurred, which, in the
opinion of the Agent, render the continued operation of the
Facilities or the Plant uneconomic;

          (e)  any court or administrative body shall enter a
judgment, order or decree requiring any Company to cease, or
dispose of, all or any substantial part of its operations of the
Facilities or the Plant to such extent that, in the opinion of the
Agent, any Company is or will be thereby prevented from carrying on
its normal operations of the Facilities or the Plant for a period
of six or more consecutive months; or

          (f)  as a result of any change in the Constitution of the
State of Texas or the Constitution of the United States of America
or of any legislative or administrative action (whether state or
federal), or of any final decree, judgment or order of any court or
administrative body (whether state or federal), the obligations of
any Company under the Agreement shall have become unenforceable or
impossible of performance in any material respect in accordance
with the intent and purpose of the parties as expressed in the
Agreement (as specified in the Indenture).

     Extraordinary Mandatory Redemption

     The Bonds are subject to mandatory redemption in whole or in
part at any time if such partial redemption will preserve the
exemption from federal income taxation of interest on the remaining
Bonds Outstanding, at a redemption price equal to the principal
amount thereof together with unpaid interest accrued to the date
fixed for redemption, and without premium, if (a) a final decree or
judgment of any federal court, in which the Agent participates to
the extent it deems sufficient, or (b) a final action by the
Internal Revenue Service, in proceedings in which the Agent
participates to the extent it deems sufficient, determines that the
interest paid or payable on any Bonds to other than, as provided in
the Internal Revenue Code of 1986, as amended (the "Code"), a
"substantial user" of the Facilities or a "related person" is or
was includable in the gross income of the owner thereof for federal
income tax purposes under the Code, as a result of the failure by
any Company to observe or perform any covenant, condition or
agreement on its part to be observed or performed under the
Agreement or the inaccuracy of any representation by any Company
under the Agreement; provided, however, that no decree or judgment
by any court or action by the Internal Revenue Service shall be
considered final unless the Registered Owner involved in such
proceeding or action (i) gives the Agent and the Trustee prompt
written notice of the commencement thereof and (ii) if the Agent
agrees to pay all expenses in connection therewith and to indemnify
such Registered Owner against all liabilities in connection
therewith, offers the Agent the opportunity to control the defense
thereof.  Any such redemption shall be made on a date determined by
the Trustee not more than 180 days after the date of such final
decree, judgment or action.  The Trustee shall give the Issuer and
the Agent not less than 45 days written notice of such date.

     Notice of Redemption

     Not less than thirty (30) days or more than sixty (60) days
prior to any date fixed for redemption of Bonds, the Trustee shall
give notice of any redemption by sending such notice by (i) first-
class mail to the Owner of each Bond to be redeemed in whole or in
part, (ii) by certified mail, return receipt requested, to DTC (so
long as it owns all the Bonds), and upon request, to any person or
entities which provide evidence acceptable to the Trustee that such
person has a legal or beneficial interest in at least $1,000,000 in
principal amount of the Bonds, and (iii) by certified mail, return
receipt requested, or by overnight delivery, received by the
registered depositories at least two (2) days prior to the general
publication date for such redemption notices and to be received by
at least two (2) of the national information services that
disseminate bond redemption notices on or before the general
mailing date for such notices; provided, however, that the failure
to send, mail or receive such notice described above, or any defect
therein or in the sending or mailing thereof, with respect to any
Bond shall not affect the validity or effectiveness of the
proceedings for the redemption of any other Bond.  In addition,
within sixty (60) days after the redemption date an additional
redemption notice shall be sent to any Owner of the Bonds who has
not surrendered Bonds for redemption during the thirty (30) day
period following the redemption date and to any person or entities
having legal or beneficial ownership interest in at least
$1,000,000 in principal amount of such Bonds which have not been
surrendered.

     All notices of redemption shall state (i) the redemption date,
(ii) the redemption price, (iii) the identification, including
complete designation (including series) and issue date of the Bonds
and the CUSIP number, certificate number (and in the case of
partial redemption, the respective principal amounts), interest
rates and maturity dates of the Bonds to be redeemed, (iv) that on
the redemption date the redemption price will become due and
payable upon each such Bond, and that interest thereon shall cease
to accrue from and after said date, and (v) the name and address of
the Trustee and any Paying Agent for such Bonds, including the
place where such Bonds are to be surrendered for payment of the
redemption price therefor.

     Mandatory Tender and Conversion in Lieu of Optional Redemption

     So long as no Event of Default exists under the Indenture, the
Agent may elect, on any optional redemption date for the Bonds,
beginning June 1, 2006, to convert all or any part of the Bonds to
a different interest rate Mode.  The Agent shall make such election
as specified in the Indenture and upon such election such Bonds
shall be subject to mandatory tender for purchase on such mandatory
tender date, in lieu of optional redemption, at the applicable
Purchase Price.  The Paying Agent shall give notice of such
mandatory tender for purchase to the Registered Owners of Bonds by
first class mail, not less than thirty (30) days before the
mandatory tender date.  Mandatory tender and conversion in lieu of
optional redemption is subject to certain conditions relating to
rating the Bonds and obtaining consent from MBIA Insurance
Corporation (the "Bond Insurer").  

     The Bonds will be initially issued in the "Fixed Rate Mode". 
Other than the Fixed Rate Mode, the permitted Modes for the Bonds
are "Flexible Mode," for periods of from one to 270 days, and
"Daily Mode," "Weekly Mode," "Monthly Mode," "Quarterly Mode,"
"Semiannual Mode" and "Multiannual Mode," for periods of one day,
one week, one month, three months, six months or one year or
integral multiples thereof, respectively.  Except as otherwise
provided in the Indenture, the interest rates in each Mode and the
period during which a particular Mode is in effect will be
determined by a remarketing agent to be appointed under the
Indenture.  The Mode for all or a portion of the Bonds after
conversion as described above is subject to subsequent conversion
to a different Mode from time to time at the election of the Agent
as provided in the Indenture.  Purchasers of Bonds after conversion
will receive an offering document describing the alternative Modes
and other features of the Bonds.

                     BOOK-ENTRY ONLY SYSTEM

     The Depository Trust Company ("DTC"), New York, New York, will
act as securities depository for the Bonds (the "Securities
Depository").  The Bonds will be issued as fully-registered
securities registered in the name of Cede & Co., as nominee for
DTC.  One fully-registered Bond certificate for Bonds of each Mode
will be issued in the aggregate principal amount of the Bonds of
that Mode and will be deposited with DTC.

     DTC is a limited-purpose trust company organized under the
New York Banking Law, a "banking organization" within the meaning
of the New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the New York
Uniform Commercial Code, and a "clearing agency" registered
pursuant to the provisions of Section 17A of the Securities
Exchange Act of 1934, as amended.  DTC holds securities that its
participants deposit with DTC (such participants or the
participants of any successor Securities Depository are herein
referred to as "Participants" or "DTC Participants").  DTC also
facilitates the settlement among DTC Participants of securities
transactions, such as transfers and pledges, in deposited
securities through electronic computerized book-entry changes in
DTC Participants' accounts, thereby eliminating the need for
physical movement of securities certificates.  Participants include
securities brokers and dealers, banks, trust companies, clearing
corporations and certain other organizations.  DTC is owned by a
number of its Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc. and the National
Association of Securities Dealers, Inc.  Access to the DTC system
is also available to others such as securities brokers and dealers,
banks and trust companies that clear through or maintain a
custodial relationship with a Participant, either directly or
indirectly ("Indirect Participants").  The rules applicable to DTC
and the Participants are on file with the Securities and Exchange
Commission.

     Purchases of beneficial ownership interests in the Bonds under
the DTC system must be made by or through Participants, which will
receive a credit for the Bonds on DTC's records.  The ownership
interest of each Beneficial Owner of a Bond is in turn to be
recorded on the  Participant's and Indirect Participants' records. 
Beneficial Owners will not receive written communication from DTC
of their purchase, but Beneficial Owners are expected to receive
written confirmations providing details of the transaction, as well
as periodic statements of their holdings, from the Participant or
Indirect Participant through which the Beneficial Owner entered
into the transaction.  Transfers of ownership interests of the
Bonds are to be accomplished by entries made on the books of
Participants acting on behalf of Beneficial Owners.  Beneficial
Owners will not receive certificates representing their ownership
interests in the Bonds, except in the event that use of the book-
entry system for the Bonds is discontinued as described under the
caption "Discontinuation of Book-Entry Only System."

     To facilitate subsequent transfers, all Bonds deposited with
DTC are registered in the name of DTC's partnership nominee, Cede
& Co.  The deposit of Bonds with DTC and their registration in the
name of Cede & Co. effect no change in beneficial ownership.  DTC
has no knowledge of the actual Beneficial Owners of the Bonds. 
DTC's records reflect only the identity of the Participants to
whose accounts such Bonds are credited, which may or may not be the
Beneficial Owners.  The Participants will remain responsible for
keeping account of their holdings on behalf of their customers.

     Conveyance of notices and other communications by DTC to
Participants, by Participants to Indirect Participants, and by
Participants and Indirect Participants to Beneficial Owners will be
governed by arrangements among them, subject to any statutory or
regulatory requirements as may be in effect from time to time.

     Notices of redemption of Bonds will be sent to Cede & Co.  If
less than all of the Bonds of a particular Mode are being redeemed,
DTC's practice is to determine by lot the amount of the interest of
each Participant in Bonds of such Mode to be redeemed.

     Neither DTC nor Cede & Co. will consent or vote with respect
to Bonds.  Under its usual procedures, DTC mails an "Omnibus Proxy"
to the Issuer as soon as possible after the record date.  The
"Omnibus Proxy" assigns Cede & Co.'s consenting or voting rights to
those Participants to whose accounts the Bonds are credited on the
record date identified in a listing attached to the "Omnibus
Proxy."

     Principal and interest payments on the Bonds will be made to
DTC.  DTC's practice is to credit DTC Participants' accounts on a
payment date in accordance with their respective holdings shown on
DTC's records unless DTC has reason to believe that it will not
receive payment on a payment date.  Payments by Participants to
Beneficial Owners will be governed by standing instructions and
customary practices, as in the case with securities held for the
accounts of customers in bearer form or registered in "street name"
and will be the responsibility of such Participant and not of DTC,
the Trustee, the Issuer, the Agent or the Companies, subject to any
statutory or regulatory requirements as may be in effect from time
to time.  Payments of principal and interest to DTC is the
responsibility of the Trustee.  Disbursement of such payments to
Participants is the responsibility of DTC and disbursement of such
payments to the Beneficial Owners is the responsibility of the
Participants and Indirect Participants.

     DTC may discontinue providing its services as securities
depository with respect to the Bonds at any time by giving
reasonable notice to the Issuer.  Under such circumstances, in the
event that a successor securities depository is not obtained, Bond
certificates are required to be printed and delivered as described
herein under the caption "Discontinuation of Book-Entry Only
System."

     The Issuer may decide to discontinue use of the system of
book-entry transfers through DTC or a successor securities
depository.  In that event, Bond certificates will be printed and
delivered as described herein under the caption "Discontinuation of
Book-Entry Only System."

     THE INFORMATION PROVIDED IMMEDIATELY ABOVE UNDER THIS CAPTION
HAS BEEN PROVIDED BY DTC.  NO REPRESENTATION IS MADE BY THE ISSUER,
THE AGENT, THE COMPANIES OR THE UNDERWRITERS AS TO THE ACCURACY OR
ADEQUACY OF SUCH INFORMATION PROVIDED BY DTC OR AS TO THE ABSENCE
OF MATERIAL ADVERSE CHANGES IN SUCH INFORMATION SUBSEQUENT TO THE
DATE HEREOF.

     For so long as the Bonds are registered in the name of DTC or
its nominee, Cede & Co., the Issuer, the Bond Insurer and the
Trustee will recognize only DTC or its nominee, Cede & Co., as the
Registered Owner of the Bonds for all purposes, including payments,
notices (including notices of redemption or mandatory tender) and
voting.

     Under the Indenture, payments made by the Trustee to DTC or
its nominee shall satisfy the Issuer's obligations under the
Indenture and the Companies' obligations under the Agreement to the
extent of the payments so made.

     Neither the Issuer, the Agent, the Companies, the Bond Insurer
nor the Trustee shall have any responsibility or obligation with
respect to:

          (i)  the accuracy of the records of DTC, its nominee or
     any Participant or Indirect Participant with respect to any
     beneficial ownership interest in any Bonds;

          (ii) the delivery to any Participant or Indirect
     Participant or any other person, other than an owner, as shown
     in the bond register, of any notice with respect to any Bond
     including, without limitation, any notice of redemption,
     tender, purchase or any event which would or could give rise
     to a tender or purchase right or option with respect to any
     Bond;

          (iii)     the payment to any Participant or Indirect
     Participant or any other person, other than an owner, as shown
     in the bond register, of any amount with respect to the
     principal of, premium, if any, or interest on, or the Purchase
     Price of, any Bond; or

          (iv) any consent given by DTC as Registered Owner.

     Prior to any discontinuation of the Book-Entry Only System
described above, the Issuer, the Bond Insurer and the Trustee may
treat DTC as, and deem DTC to be, the absolute owner of the Bonds
for all purposes whatsoever, including, without limitation:

          (i)  the payment of principal of, premium, if any, and
     interest on the Bonds;

          (ii) giving notices of redemption and other matters with
     respect to the Bonds;

          (iii)     registering transfers with respect to the
     Bonds; and

          (iv) the selection of Bonds for redemption.

Discontinuation of Book-Entry Only System

     In the event that the Issuer determines to remove the
Securities Depository, the Issuer will (i) appoint a successor
Securities Depository and transfer one or more separate Bond
certificates to such successor or (ii) notify the Participants of
the Securities Depository of the availability through the
Securities Depository of Bond certificates and transfer one or more
separate Bond certificates to the Participants of the Securities
Depository having Bonds credited to their accounts with the
Securities Depository.  In such event, the Bonds will no longer be
restricted to being registered in the bond register in the name of
the Securities Depository, or its nominee, but may be registered in
the name of any successor Securities Depository, or its nominee, or
in whatever name or names the Participants of the Securities
Depository receiving Bonds shall designate, in accordance with the
provisions of the Indenture.

                          THE AGREEMENT

General

     The following is a summary of certain provisions of the
Agreement.  Reference is hereby made to the Agreement in its
entirety for the detailed provisions thereof.

Use of Bond Proceeds

     The Issuer will issue the Bonds to provide funds to currently
refund the Prior Bonds.  Upon the sale of the Bonds, the Issuer
will transfer the proceeds of the Bonds to the trustee for the
Prior Bonds for deposit into the bond fund created under the
indenture for the Prior Bonds.

Installment Payments

     The Companies will make Installment Payments, in proportion to
their respective Ownership Percentages, to fund payments on the
Bonds in such amounts which, together with other moneys available
therefor in the Bond Fund created under the Indenture, will be
sufficient to pay when due the principal of, premium, if any, and
interest on the Outstanding Bonds as they shall mature, be
redeemed, be purchased or deemed purchased or otherwise become due
as provided in the Indenture.  The Companies shall make such
payments directly to the Trustee for the account of the Issuer.

     Installment Payment obligations of each Company under the
Agreement will be absolute, several and unconditional, and each
Company will make such payments free of any deductions and without
abatement, diminution or setoff.  In the event that a Company fails
to make any of such payments, the item or installment so in default
will continue as an obligation of such Company until the amount in
default has been fully paid.

Other Payments Under the Agreement

     In addition to the Installment Payments, the Companies
severally agree, in proportion to their respective Ownership
Percentages, to pay taxes, assessments and other charges of any
kind whatsoever that may at any time be lawfully levied or imposed
with respect to the Facilities or the Installment Payments under
the Agreement and all costs and expenses of the operation and
maintenance of the Facilities.  The Companies also severally agree,
in proportion to their respective Ownership Percentages, to pay
certain costs and expenses of the Issuer and the Trustee in
connection with the Bonds and to indemnify such parties against
certain liabilities arising in connection with the sale of the
Bonds and the execution and delivery of the related bond documents.

Corporate Existence

     Each Company agrees that it will not dispose of all or
substantially all of its assets as an entirety (whether by
liquidation, dissolution, or otherwise) and will not consolidate
with or merge into another corporation, or permit one or more
corporations to consolidate with or merge into it, unless the
resulting, surviving, or transferee corporation, as the case may
be, if other than WTU, PSO or CPL, as the case may be, irrevocably
and unconditionally assumes, in an instrument delivered to the
Issuer and to the Trustee, the due and punctual performance of the
obligations of WTU, PSO or CPL, as the case may be, under the
Agreement.  Upon the delivery of such an instrument, WTU, PSO or
CPL, as the case may be, shall thereupon be relieved of any further
obligation or liability under the Agreement or with respect to the
Bonds, and the resulting, surviving, or transferee corporation, as
the case may be, shall succeed to and be substituted for WTU, PSO
or CPL, as the case may be, under the Agreement with the same
effect as if such resulting or surviving corporation or transferee
had been a party to the Agreement.

Assignment

     Under certain conditions, the Agreement may be assigned by a
Company, but such assignment will not relieve such Company from
primary liability for any of its several obligations under the
Agreement.  No assignment will be effective without a Favorable
Opinion being furnished to the Issuer and the Trustee, together
with notice of such assignment.

Defaults and Remedies

     The Agreement provides that the occurrence and continuation of
any one of the following shall constitute an "Event of Default"
thereunder:

          (a)  failure by any of the Companies to pay its Ownership
     Percentage of Installment Payments with respect to principal
     of or premium on any Bond at the times specified therein;

          (b)  failure by any of the Companies to pay its Ownership
     Percentage of Installment Payments with respect to interest on
     any Bond at the times specified therein and the continuation
     of such failure for a period of 60 days or more;

          (c)  failure by any of the Companies to pay its Ownership
     Percentage of Installment Payments with respect to the
     Purchase Price of any Bond at the times specified therein and
     the continuation of such failure for a period of one Business
     Day or more after notice thereof shall have been given by the
     Trustee to the Agent and the Issuer;

          (d)  failure by any of the Companies to observe and
     perform any covenant, condition or agreement on its part
     required to be observed or performed in the Agreement, other
     than as referred to in (a), (b) or (c) above, for a period of
     90 days after receipt by the Agent of written notice
     specifying such failure and requesting that it be remedied,
     given to the Agent by the Issuer or the Trustee, unless the
     Issuer and the Trustee shall agree in writing to an extension
     of such time prior to its expiration; provided, however, that
     if the failure stated in the notice can, in the reasonable
     judgment of the Agent, be corrected, but cannot be corrected
     within the applicable period, the Issuer and the Trustee will
     not unreasonably withhold their consent to an extension of
     such time if corrective action is instituted within the
     applicable period and diligently pursued until the default is
     corrected;

          (e)  certain events of dissolution, liquidation,
     insolvency, bankruptcy or reorganization involving any of the
     Companies; or

          (f)  the occurrence of an "Event of Default" under the
     Indenture.

     The provisions of paragraph (d) above are subject to the
following limitations: if by reason of acts of God, strikes,
lockouts or other industrial disturbances; acts of public enemies;
orders or regulations of any kind of the government of the United
States of America or of the State of Texas or any of their
departments, agencies, political subdivisions, or officials, or any
civil or military authority; insurrections; riots; epidemics;
landslides; lightning; earthquakes; tidal waves; fires; hurricanes;
tornadoes; blue northers; other storms; floods; washouts; droughts;
arrests; restraints of government and people; civil disturbances;
explosions; breakage or accident to machinery, transmission pipes,
transmission facilities or canals; partial or entire failure of
utilities; shortages of labor, material, supplies or
transportation; or any other cause or event not reasonably within
the control of the Companies (collectively, "events of force
majeure"), the Companies are unable in whole or in part to carry
out the agreements on the Companies' part herein contained, the
Companies shall not be deemed in default during the continuance of
such inability.  The Companies, however, will use their best
efforts to remedy with all reasonable dispatch the cause or causes
preventing the Companies from carrying out such agreements;
provided, that the settlement of strikes, lockouts and other
industrial disturbances shall be entirely within the discretion of
the Companies, and the Companies shall not be required to make
settlement of strikes, lockouts, and other industrial disturbances
by acceding to the demands of the opposing party or parties when
such course is, in the judgment of the Agent, unfavorable to the
Companies.  The occurrence of any event of force majeure shall not
suspend or otherwise abate, and the Companies shall not be relieved
from, any obligation under this Agreement to the extent that the
failure of the Companies to observe or perform any such obligation
would result in the failure to pay when due the principal of,
premium, if any, interest on, or the Purchase Price for, the Bonds
or would result in the interest on any Bonds becoming includable in
the gross income of the owners thereof for federal income tax
purposes.

     The above provisions, however, are subject to the conditions
that, after any such Event of Default, subject to and as provided
in the Indenture, the Trustee may waive such Event of Default and
rescind and annul any remedial step theretofore taken by it or by
the Issuer with respect to such default and its consequences; but
no such waiver, rescission or annulment shall extend to or affect
any subsequent default or impair any right or remedy consequent
thereon.

     Whenever any Event of Default under the Agreement shall have
occurred and is continuing, the Issuer, with the consent of the
Trustee, or the Trustee may take any one or more of the following
remedial steps but only if acceleration of the principal amount of
the Bonds has been declared pursuant to the Indenture:

          (a)  By notice in writing to the Agent, declare the
     unpaid Installment Payments to be due and payable immediately,
     if concurrently with or prior to such notice the unpaid
     principal amount of the Bonds has been declared to be due and
     payable under the Indenture, and upon any such declaration the
     Installment Payments payable under the Agreement shall become
     and shall be immediately due and payable in the amount equal
     to the principal of and all accrued interest on the Bonds
     (without premium); provided, however, that an Event of Default
     shall be deemed waived and a declaration accelerating payment
     of unpaid Installment Payments payable under the Agreement
     shall be deemed rescinded without further action on the part
     of the Trustee or the Issuer upon any rescission by the
     Trustee of the corresponding declaration of acceleration of
     the Bonds under the Indenture.

          (b)  Whatever action at law or in equity may appear
     necessary or desirable to collect the payment and other
     amounts then due or to enforce performance and observance of
     any obligation, agreement or covenant of any of WTU, PSO or
     CPL under the Agreement.

     The Companies have covenanted that, in case an Event of
Default shall occur with respect to the payment of any Installment
Payment payable then, upon demand of the Trustee, the Companies
will severally pay, in proportion to their respective Ownership
Percentages, to the Trustee the whole amount that then shall have
become due and payable, with interest (to the extent permitted by
law) on such amount, at the rate of interest borne by the Bonds at
the time of such failure, from the due date thereof until paid.

     In case any Company shall fail to pay such amounts upon such
demand, the Trustee shall be entitled and empowered to institute
any action or proceeding at law or in equity for the collection of
the sums so due and unpaid, and may prosecute any such action or
proceeding to judgment or final decree, and may enforce any such
judgment or final decree against such Company and collect, in the
manner provided by law out of the property of such Company, the
moneys adjudged or decreed to be payable.

Certain Covenants Regarding Arbitrage and Tax Exemption 

     The Issuer and the Companies have agreed not to knowingly take
any action or omit to take any action, which would result in a loss
of the exemption from federal income taxation of interest on the
Bonds by virtue of the Bonds being considered "arbitrage bonds"
within the meaning of Section 148 of the Code.  The Issuer and the
Companies have agreed to refrain from any action which would
adversely affect, and to take such action to assure, the treatment
of the Bonds as obligations described in Section 103(a) of the
Code, the interest on which is not includable in the "gross income"
of the holder (other than the income of a "substantial user" of the
Facilities or a "related person" within the meaning of Section
147(a) of the Code) for purposes of federal income taxation.

Amendment of Agreement

     The Agreement may be amended by written agreement of the
Issuer, the Agent, each Company and the Bond Insurer, provided that
no amendment may be made which would adversely affect the rights of
the Owners of any of the Outstanding Bonds without the consent of
the Owners of a majority in aggregate principal amount of the Bonds
then Outstanding; provided, however, that no amendment may be made
which would (i) decrease the amounts payable under the Agreement;
(ii) change the date of payment or prepayment provisions under the
Agreement; or (iii) change the amendment provisions of the
Agreement without the consent of all of the Owners of the Bonds
adversely affected thereby; and provided further that the Agreement
may be amended by written agreement of the Issuer and the Companies
in order to make conforming changes with respect to certain
amendments made to the Indenture.  Notwithstanding the foregoing,
the Ownership Percentage of each of WTU, PSO and CPL may be changed
by agreement among WTU, PSO and CPL, without notice to, or the
approval or consent of, the holders of the Bonds, provided that the
aggregate Ownership Percentage of WTU, PSO and CPL will at all
times equal 100%.

                          THE INDENTURE

General

     The following is a summary of certain provisions of the
Indenture.  Reference is hereby made to the Indenture in its
entirety for the detailed provisions thereof.

Bond Fund

     The Indenture creates and establishes with the Trustee a
separate trust fund designated the "Red River Authority of Texas
Pollution Control Revenue Refunding Bonds (West Texas Utilities
Company, Public Service Company of Oklahoma and Central Power and
Light Company Oklaunion Project) Series 1996 Bond Fund" (the "Bond
Fund"), which will be used solely for the payment of the principal
of, premium, if any, and interest on the Bonds.  All Installment
Payments made by the Companies in connection with principal of,
premium, if any, and interest on the Bonds will be made to the
Trustee for deposit in the Bond Fund.  There shall be deposited
into the Bond Fund, when received: (i) accrued interest, if any, on
the Bonds from the date thereof to the date of delivery to the
initial purchaser thereof; (ii) all payments specified in the
Agreement (except for certain payments of fees, expenses, and
indemnification arising out of the Issuer's Unassigned Rights);
(iii) all moneys required to be so deposited in connection with any
redemption of Bonds; (iv) any amounts directed to be transferred
into the Bond Fund pursuant to any provision of the Indenture, and
(v) all other moneys when received by the Trustee which are
required to be deposited into the Bond Fund or which are
accompanied by directions that such moneys are to be paid into the
Bond Fund.

     Moneys held in the Bond Fund shall be used solely for the
payment of the principal of, premium, if any, and interest on the
Bonds on the dates due for the payment or redemption thereof.  The
Issuer has authorized and directed the Trustee to withdraw
sufficient funds from the Bond Fund to pay the principal of,
premium, if any, and interest on the Bonds as the same become due
and payable, which authorization and direction the Trustee has
accepted.

Investment

     Except as provided in the Indenture, any moneys held as part
of the Bond Fund shall be invested or reinvested by the Trustee as
provided in written instructions of the Agent solely in Permitted
Investments.

Moneys Held in Trust

     All moneys required to be deposited with or paid to the
Trustee for the account of any fund under the Indenture shall be
held by the Trustee in trust and, except for (i) moneys in the Bond
Purchase Fund and the Rebate Fund, and (ii) moneys deposited with
or paid to the Trustee for the redemption of Bonds, notice of the
redemption for which has been duly given, shall, while held by the
Trustee, be part of the trust estate and be subject to the security
interest created by the Indenture.

Events of Default and Remedies

     The Indenture provides that each of the following constitutes
an "Event of Default" thereunder:

          (a)  default in the due and punctual payment of the
     principal of or premium, if any, on any Outstanding Bond, as
     the same shall become due and payable, whether at the stated
     maturity thereof, upon any proceedings for redemption, or upon
     the maturity thereof by declaration of acceleration;

          (b)  default in the due and punctual payment of the
     interest on any Outstanding Bond, as the same shall become due
     and payable, and the continuation of such default for a period
     of 60 days or more;

          (c)  default in the due and punctual payment of the
     Purchase Price of any Outstanding Bond, as the same shall
     become due and payable and the continuation of such default
     for a period of one Business Day or more;

          (d)  default by the Issuer in its performance or
     observance of any of the other covenants, agreements or
     conditions contained in the Indenture, and the continuation
     thereof without corrective action for a period of 90 days
     after receipt by the Issuer and the Agent of notice given by
     the Trustee or the Owners of not less than 25% in aggregate
     principal amount of all Bonds Outstanding as specified in the
     Indenture; or

          (e)  an Event of Default (as defined in the Agreement)
     has occurred and is continuing under the Agreement. 

If any Event of Default occurs and is continuing, the Trustee may,
and upon request of the owners of at least 25% in principal amount
of all Bonds then Outstanding shall, by notice in writing to the
Issuer and the Agent, declare the principal of all Bonds then
Outstanding to be immediately due and payable, and upon such
declaration the said principal, together with interest accrued
thereon to the date of acceleration, shall become due and payable
immediately at the place of payment provided therein, anything in
the Indenture or in the Bonds to the contrary notwithstanding. 
Upon the occurrence of any such acceleration, the Trustee shall
immediately declare all Installment Payments to be due and payable
immediately.

     If, after the principal of the Bonds has become due and
payable, all arrears of interest upon the Bonds are paid by the
Issuer, and the Issuer also performs all other things in respect to
which it may have been in default under the Indenture and pays the
reasonable charges of the Trustee and the Bondholders, including
reasonable and necessary attorneys' fees, then, and in every such
case, the owners of a majority in principal amount of the Bonds
then Outstanding, by notice to the Issuer and to the Trustee, may
annul such acceleration and its consequences.  No such annulment
shall extend to or affect any subsequent default or impair any
right or remedy consequent thereon.

     Upon the occurrence of an Event of Default, the Trustee may
pursue any available remedy by suit at law or in equity to enforce
the payment of the principal of, premium, if any, and interest on
the Bonds then Outstanding, and the performance by the Issuer of
its obligations under the Indenture, including, without limitation,
the following:  (a) by mandamus, or other suit, action or
proceeding at law or in equity, enforce all rights of the
Bondholders and require the Issuer to carry out its agreements
under the Indenture and the Acts; (b) bring suit upon the Bonds;
(c) by action, suit or proceeding at law or in equity, require the
Issuer to account as if it were the trustee of an express trust for
the Bondholders; or (d) by action, suit or proceeding at law or in
equity, enjoin any acts or things which may be unlawful or in
violation of the rights of the Bondholders.

MBIA Insurance Corporation Deemed to be a Bondholder

     Notwithstanding any provision of the Indenture to the
contrary, the Bond Insurer shall at all times be deemed the
exclusive owner of all Bonds for the purposes of all approvals,
consents, waivers, institution of any action, and the direction of
all remedies.  No acceleration shall be permitted, and no Event of
Default shall be waived, without the Bond Insurer's consent.  The
Bond Insurer shall have the right to direct all remedies pursuant
to the Indenture.

Defeasance

     Subject to the consent of the Bond Insurer, any Bond shall be
deemed to have been paid and discharged when payment of the
principal of and premium, if any, on such Bond plus the interest
thereon to the due date thereof (whether such due date be by reason
of maturity or upon redemption as provided in the Indenture or
otherwise) either (a) shall have been made in accordance with the
terms of the Indenture or (b) shall have been provided for by
irrevocably depositing with the Trustee, in trust solely for such
payment, any combination of (1) sufficient moneys to make such
payment and/or (2) Government Obligations not subject to redemption
or prepayment and maturing as principal and interest in such
amounts as in the opinion of an independent certified public
accountant delivered to the Trustee are sufficient to make such
payment without reinvestment and to pay all fees and expenses in
connection therewith.

Discharge of Lien

     When all of the Bonds have been paid or deemed paid and the
Issuer is not in default under any of the covenants and promises
contained in such Bonds and the Indenture, and if the Issuer shall
pay or cause to be paid to the Trustee all sums of money due or to
become due according to the Indenture or of the Bonds and of the
Agreement, then the rights under the Indenture will become null and
void; provided, however, that the rights of the Trustee under the
Indenture to receive its fees, charges and expenses shall survive
the discharge of the Indenture until paid in full.  See the caption
"Defeasance" above for a discussion of the conditions under which
the Bonds will be deemed to have been paid.

The Trustee; New York Paying Agent

     To the extent permitted by law, the Trustee may invest in and
treat itself as any other holder of the Bonds.  The Trustee may
resign at any time after notice to the Issuer, the Agent and the
Bondholders, such resignation to take effect only upon the
appointment of a successor Trustee.  The Trustee may be removed at
any time by written notice signed by the Issuer and the Agent and
delivered to the Trustee and the Bondholders.  Such removal shall
take effect only upon the appointment of a successor Trustee. 
Every successor trustee may be appointed by the Issuer with the
consent of the Agent and shall be a bank or trust company which
(i) is organized as a corporation or banking association and doing
business under the laws of the United States of America or any
state thereof, (ii) is authorized under such laws to exercise
corporate trust powers and to perform all the duties imposed upon
it by the Indenture and the Agreement, (iii) is subject to
supervision or examination by federal or state authority, (iv) has
combined capital and surplus of at least $50,000,000, (v) shall not
have become incapable of acting or have been adjudged a bankrupt or
an insolvent or have had a receiver appointed for itself or for any
of its property or have had a public officer take charge or control
of it or its property or affairs for the purpose of rehabilitation,
conservation or liquidation and (vi) must be an institution rated
at least "Baa3" by Moody's (or Moody's shall have provided written
evidence that such successor Trustee is otherwise acceptable to
Moody's) if the Bonds are then rated by Moody's, and at least "BBB-
" or "A-3" by S&P (or S&P shall have provided written evidence that
such successor Trustee is otherwise acceptable to S&P) if the Bonds
are then rated by S&P.  Should the Trustee cease to be eligible to
act as trustee under the Indenture, it shall promptly notify the
Owners of all Bonds then Outstanding, the Issuer and the Agent of
such fact.  The Issuer may appoint a temporary trustee until the
appointment of such successor.

     The Paying Agent is required to maintain an office, or have an
agent with an office, in New York City at all times that any Bonds
are outstanding.

Additional Notices

     Upon written request of any Owner of Bonds in an aggregate
principal amount of at least $1,000,000 (or any person or entity
which provides written evidence acceptable to the Trustee that such
person or entity has a legal or beneficial interest in Bonds in an
aggregate principal amount of at least $1,000,000), the Trustee
shall give an additional copy of any notice to be given by the
Trustee under the Indenture by first-class mail to a second address
specified by such Owner, person or entity.  Any such additional
notices shall be given simultaneously with the original notices.

     Upon written request of any person or entity which provides
evidence acceptable to the Trustee that such person or entity has
a legal or beneficial interest in at least $1,000,000 in principal
amount of the Bonds, the Trustee shall, for the calendar year in
which such request is received, provide one or more of the
following as requested to such person or entity:  (i) notices of
redemption; (ii) notices of default; (iii) copies of all notices to
which such person or entity is entitled under the Indenture to a
specific second address; and (iv) outstanding balances by maturity,
redemption history, including redemption date, amount and source of
funds and distribution of the call to maturity.

Supplemental Indentures

     The Issuer and the Trustee, with the written consent of the
Agent and the Bond Insurer, but without the consent of or notice to
the Bondholders, may enter into an indenture or indentures
supplemental to the Indenture, for any of the following purposes:

          (a)  to cure any ambiguity, formal defect or omission in
     the Indenture or to make such other changes which shall not
     have a material adverse effect upon the interests of the
     Bondholders;

          (b)  to grant to or confer upon the Trustee, for the
     benefit of the Bondholders, any additional rights, remedies,
     powers or authorities, or any additional security, that may
     lawfully be granted to or conferred upon the Bondholders or
     the Trustee;

          (c)  to subject to the Indenture additional revenues,
     properties or collateral;

          (d)  to modify, amend or supplement the Indenture, or any
     indenture supplemental thereto, in such manner as to permit
     the qualification thereof under the Trust Indenture Act of
     1939, as amended, or any similar federal statute hereafter in
     effect, or to permit the qualification of the Bonds for sale
     under the securities laws of any of the states of the United
     States and, if the Issuer so determines, to add to the
     Indenture or any indenture supplemental thereto such other
     terms, conditions and provisions as may be permitted by the
     Trust Indenture Act of 1939, as amended, or any similar
     federal statute;

          (e)  to add to the covenants and agreements of the Issuer
     contained in the Indenture other covenants and agreements
     thereafter to be observed for the protection of the
     Bondholders or to surrender or limit any right, power or
     authority therein reserved to or conferred upon the Issuer;

          (f)  effective upon any Conversion Date to a new Mode, to
     make any amendment affecting only the Bonds being converted,
     including revision to Authorized Denominations; 

          (g)  to add provisions relating to the partial conversion
     of Bonds to a new Mode;

          (h)  to conform the Indenture to the requirements of the
     Rating Agencies;

          (i)  to add or modify provisions permitting a mandatory
     tender of Bonds in lieu of redemption; and

          (j)  to add provisions permitting the addition of a
     credit facility or a liquidity facility.

     Exclusive of the purposes described in subparagraphs (a)
through (j) above, the Owners of a majority in aggregate principal
amount of the Bonds then Outstanding will have the right, from time
to time, to approve any supplemental indenture deemed necessary and
desirable by the Issuer for the purposes of modifying, altering,
amending, adding to or rescinding any of the terms or provisions
contained in the Indenture or any supplemental indenture.  No
modification or alteration may be made without the consent of the
holders of all Bonds then Outstanding which permits (i) an
extension of the maturity of the principal of, or the time for
payment of any redemption premium or interest on, any Bond or a
reduction in the principal amount of any Bond, or the rate of
interest or redemption premium thereon, or a reduction in the
amount of, or extension of the time of any payment required by, any
Bond; (ii) a privilege or priority of any Bond over any other Bond
(except as provided in the Indenture); (iii) a reduction in the
aggregate principal amount of the Bonds required for consent to
such a supplemental indenture; (iv) the deprivation of the Owner of
any Bond then Outstanding of the lien created by the Indenture; or
(v) the amendment of the limitations described in this paragraph.


         THE MBIA INSURANCE CORPORATION INSURANCE POLICY

     The following information has been furnished by the Bond
Insurer for use in this Official Statement.  Reference is made to
Appendix F to this Official Statement for a specimen of the Bond
Insurer's policy.

     The Bond Insurer's policy unconditionally and irrevocably
guarantees the full and complete payment required to be made by or
on behalf of the Issuer to the Paying Agent or its successor of an
amount equal to (i) the principal of (either at the stated maturity
or by a mandatory redemption upon the occurrence of a determination
of taxability) and interest on, the Bonds as such payments shall
become due but shall not be so paid (except that in the event of
any acceleration of the due date of such principal by reason of
mandatory or optional redemption or acceleration resulting from
default or otherwise, other than a mandatory redemption upon the
occurrence of a determination of taxability, the payments
guaranteed by the Bond Insurer's policy shall be made in such
amounts and at such times as such payments of principal would have
been due had there not been any such acceleration); and (ii) the
reimbursement of any such payment which is subsequently recovered
from any owner of the Bonds pursuant to a final judgment by a court
of competent jurisdiction that such payment constitutes an
avoidable preference to such owner within the meaning of any
applicable bankruptcy law (a "Preference").

     The Bond Insurer's policy does not insure against loss of any
prepayment premium which may at any time be payable with respect to
any Bond.  The Bond Insurer's policy does not, under any
circumstance, insure against loss relating to:  (i) optional or
mandatory redemptions (other than a mandatory redemption upon the
occurrence of a determination of taxability); (ii) any payments to
be made on an accelerated basis; (iii) payments of the purchase
price of Bonds under tender by an owner thereof; or (iv) any
Preference relating to (i) through (iii) above.  The Bond Insurer's
policy also does not insure against nonpayment of principal of or
interest on the Bonds resulting from the insolvency, negligence or
any other act or omission of the Paying Agent or any other paying
agent for the Bonds.

     Upon receipt of telephonic or telegraphic notice, such notice
subsequently confirmed in writing by registered or certified mail,
or upon receipt of written notice by registered or certified mail,
by the Bond Insurer from the Paying Agent or any owner of a Bond
the payment of an insured amount for which is then due, that such
required payment has not been made, the Bond Insurer on the due
date of such payment or within one business day after receipt of
notice of such nonpayment, whichever is later, will make a deposit
of funds, in an account with State Street Bank and Trust Company,
N.A., in New York, New York, or its successor, sufficient for the
payment of any such insured amounts which are then due.  Upon
presentment and surrender of such Bonds or presentment of such
other proof of ownership of the Bonds, together with any
appropriate instruments of assignment to evidence the assignment of
the insured amounts due on the Bonds as are paid by the Bond
Insurer, and appropriate instruments to effect the appointment of
the Bond Insurer as agent for such owners of the Bonds in any legal
proceeding related to payment of insured amounts on the Bonds, such
instruments being in a form satisfactory to State Street Bank and
Trust Company, N.A., State Street Bank and Trust Company, N.A.
shall disburse to such owners or the Paying Agent payment of the
insured amounts due on such Bonds, less any amount held by the
Paying Agent for the payment of such insured amounts and legally
available therefor.

further explanation as to the significance of the above ratings may
be obtained only from the applicable rating agency.

     The above ratings are not recommendations to buy, sell or hold
the Bonds, and such ratings may be subject to revision or
withdrawal at any time by the rating agencies.  Any downward
revision or withdrawal of any of the above ratings may have an
adverse effect on the market price of the Bonds.  The Bond Insurer
does not guaranty the market price of the Bonds nor does it
guaranty that the ratings on the Bonds will not be revised or
withdrawn.

Disclosure of Guaranty Fund Non Participation

     In the event the Bond Insurer is unable to fulfill its
contractual obligation under the policy or contract or application
or certificate or evidence of coverage, the policyholder or
certificateholder is not protected by an insurance guaranty fund or
other solvency protection arrangement.



                           TAX MATTERS

     On the date of the initial delivery of the Bonds, McCall,
Parkhurst & Horton L.L.P., Dallas, Texas, Bond Counsel, will render
its opinion that, in accordance with statutes, regulations,
published rulings and court decisions existing on the date thereof,
(1) interest on the Bonds will be excludable from the "gross
income" of the holders thereof, except for any holder who is
treated pursuant to Section 103(b)(13) of the Internal Revenue Code
of 1954 as a "substantial user" of the Facilities or a "related
person" to such user and (2) the Bonds will not be treated as
"specified private activity bonds" the interest on which would be
included as an alternative minimum tax preference item under
Section 57(a)(5) of the Code.  Except as stated above, Bond Counsel
will express no opinion as to any other federal, state or local tax
consequences of the purchase, ownership or disposition of the
Bonds.  See Appendix E -- Form of Opinion of Bond Counsel.

     In rendering its opinion, Bond Counsel will rely upon (a)
information furnished by the Companies, and, particularly, written
representations of officers and agents of the Companies with
respect to certain material facts that are solely within their
knowledge relating to the use of the proceeds of the Bonds and the
Prior Bonds, and the construction and use of the Facilities, and
(b) covenants of the Issuer and the Companies with respect to
arbitrage, the application of the proceeds to be received from the
issuance and sale of the Bonds and the Prior Bonds and certain
other matters.  Failure of the Issuer or the Companies to comply
with these representations or covenants could cause the interest on
the Bonds to become includable in gross income retroactively to the
date of issuance of the Bonds.

     The law upon which Bond Counsel has based its opinion is
subject to change by Congress and to subsequent judicial and
administrative interpretation by the courts and the Department of
the Treasury.  There can be no assurance that such law or the
interpretation thereof will not be changed in a manner which would
adversely affect the tax treatment of the purchase, ownership or
disposition of the Bonds.

Collateral Federal Income Tax Consequences

     The following discussion is a summary of certain collateral
federal income tax consequences resulting from the purchase,
ownership or disposition of the Bonds.  This discussion is based on
existing statutes, regulations, published rulings and court
decisions, all of which are subject to change or modification,
retroactively.
     
     The following discussion is applicable to investors, other
than those who are subject to special provisions of the Code, such
as financial institutions, property and casualty insurance
companies, life insurance companies, individual recipients of
Social Security or Railroad Retirement benefits, certain S
corporations with Subchapter C earnings and profits, taxpayers
claiming an earned income tax credit and taxpayers who may be
deemed to have incurred or continued indebtedness to purchase tax-
exempt obligations.

     INVESTORS, INCLUDING THOSE WHO ARE SUBJECT TO SPECIAL
PROVISIONS OF THE CODE, SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO
THE TAX TREATMENT WHICH MAY BE ANTICIPATED TO RESULT FROM THE
PURCHASE, OWNERSHIP AND DISPOSITION OF TAX-EXEMPT OBLIGATIONS
BEFORE DETERMINING WHETHER TO PURCHASE THE BONDS.

     Interest on the Bonds will be includable as an adjustment for
"adjusted earnings and profits" to calculate the alternative
minimum tax imposed on corporations by Section 55 of the Code. 
Section 55 of the Code imposes a tax equal to 20 percent of the
taxpayer's "alternative minimum taxable income" if the amount of
such alternative minimum tax is greater than the taxpayer's regular
income tax for the taxable year.

     Interest on the Bonds is includable in the "alternative
minimum taxable income" of a corporation (other than a regulated
investment company or a real estate investment trust) for purposes
of determining the environmental tax imposed by Section 59A of the
Code.  Section 59A of the Code imposes on a corporation an
environmental tax, in addition to any other income tax imposed by
the Code, equal to 0.12 percent of the excess of the modified
alternative minimum taxable income of such corporation for the
taxable year over $2,000,000.

     Interest on the Bonds may be subject to the "branch profits
tax" imposed on the effectively-connected earnings and profits of
a foreign corporation doing business in the United States.

     Under the Code, holders of tax-exempt obligations, such as the
Bonds, may be required to disclose interest received or accrued
during each taxable year on their returns of federal income
taxation.

     Section 1276 of the Code provides for ordinary income tax
treatment of gain recognized upon the disposition of a tax-exempt
obligation, such as the Bonds, if such obligation was acquired at
a "market discount" and if the fixed maturity of such obligations
is equal to, or exceeds, one year from the date of issue.  Such
treatment applies to "market discount bonds" to the extent such
gain does not exceed the accrued market discount of such bonds,
although for this purpose, a de minimis amount of market discount
is ignored.  A "market discount bond" is one which is acquired by
the holder at a purchase price which is less than the stated
redemption price at maturity.  The "accrued market discount" is the
amount which bears the same ratio to the market discount as the
number of days during which the holder holds the obligation bears
to the number of days between the acquisition date and the final
maturity date.

State, Local and Foreign Taxes

     Investors should consult their own tax advisors concerning the
tax implications of the purchase, ownership or disposition of the
Bonds under applicable state or local laws.  Foreign investors
should also consult their own tax advisors regarding the tax

passed upon for the Issuer by the firm of Gibson & Hotchkiss, a
Professional Corporation, as counsel to the Issuer.  McCall,
Parkhurst & Horton L.L.P. has not participated in the preparation
of, or examined (and they therefore will express no opinion on and
assume no responsibility for), the contents of this Official
Statement, other than as described above, and it has not considered
it necessary to do so in order to render its opinions.

     Certain legal matters will be passed upon for the Companies by
their counsel, Milbank, Tweed, Hadley & McCloy, New York, New York

Inc. (the "Underwriters") have jointly and severally agreed to

delivery.  Under the terms of the Bond Purchase Agreement dated
July 30, 1996 between the Underwriters and the Issuer, the
Underwriters have agreed, subject to the approval of certain legal
matters by counsel and to certain other conditions, to purchase all
of the Bonds if any such Bonds are purchased.  The Companies have
severally agreed to pay the Underwriters a fee equal to .831% of
the principal amount of the Bonds.  The Bonds may be offered and
sold to certain dealers (including dealers depositing such Bonds
into investment accounts) and others at prices lower than the
public offering price set forth on the cover page hereof.  After
such Bonds are released for sale to the public, the offering price
and other selling terms may from time to time be varied by the
Underwriters.

     The Company has agreed to indemnify the Underwriters against
or to contribute toward certain liabilities, including liabilities
under federal securities laws.

                      CONTINUING DISCLOSURE

     Each Company has made certain undertakings to provide annual
financial statements of such Company (commencing with the fiscal
year of such Company ended December 31, 1996) and notice of certain
material events relating to the Bonds to each nationally recognized
municipal securities information repository or, in certain cases,
the Municipal Securities Rulemaking Board, and the appropriate
state information depository, if any, in each case to the extent
required by Rule 15c2-12 (the "Rule") promulgated by the Securities
and Exchange Commission pursuant to the Securities Exchange Act of
1934, as amended.  Each Company has made such covenants solely for
the purpose of enabling the Underwriters to comply with the Rule
and such covenants do not constitute an acknowledgement by such
Company of the validity of the Rule and are valid and binding only
to the extent that the Rule is valid.  Each Company expressly
reserves the right to contest the validity of all or any portion of
the Rule, including, without limitation, as a defense in any
action.  The Companies and their officers and directors shall have
no liability in respect of such covenants except to the extent
required for such covenants to satisfy the requirements imposed by
the Rule.

                       RECENT DEVELOPMENTS

     CSW, WTU's parent company, is performing a strategic review
in conjunction with its continuing efforts to better position
itself to meet increased competition in the electric utility
industry.  As part of its continuing strategic review, CSW has
evaluated certain investments and contingencies, including WTU's
investment in plant sites, engineering studies and lignite
reserves.  As previously disclosed, WTU has made approximately
$15 million of such investments.  During the quarter ended June
30, 1996, WTU recorded an after-tax, non-cash reserve of
approximately $11 million primarily in respect of such
investments.  As a result of recording such reserve, WTU
experienced a loss for the second quarter of 1996.  However,
there could be a positive cash flow impact resulting from any tax
benefits generated by such reserves.  The reserves will not have
a material adverse effect on WTU's ongoing results of operations
or financial condition.


                      CONSTRUCTION PROGRAM

     WTU's capital expenditures for 1996-1998, including
allowance for funds used during construction ("AFUDC"), are
estimated at $42 million, $42 million and $43 million,
respectively.  WTU anticipates that the majority of the funds
required for its 1996-1998 capital expenditure program will be
provided from internal sources.  These estimates are subject to
change due to numerous factors, including load growth, escalation
of construction costs, changes in environmental regulation,
delays from regulatory hearings, adequacy of rate relief and the
availability of necessary external capital.


                             EXPERTS

     The audited financial statements and schedules of WTU
included in its Annual Report on Form 10-K for the year ended
December 31, 1995, which has been incorporated herein by
reference, have been examined by Arthur Andersen LLP, independent
public accountants, as indicated in their report dated
February 28, 1996 with respect thereto, which has been incor-
porated herein by reference, in reliance upon the authority of
said firm as experts in accounting and auditing in giving said
report.

                       RECENT DEVELOPMENTS

     CSW, CPL's parent company, is performing a strategic review in
conjunction with its continuing efforts to better position itself to meet
increased competition in the electric utility industry.  As part of its
continuing strategic review, CSW has evaluated certain investments and
contingencies, including CPL's investment in plant sites, engineering studies
and lignite reserves.  As previously disclosed, CPL has made approximately $24
million of such investments.  During the quarter ended June 30, 1996, CPL
recorded an after-tax, non-cash reserve of approximately $15.6 million
primarily in respect of such investments.  There could be a positive cash flow
impact resulting from any tax benefits generated by such reserves.  The
reserves will not have a material adverse effect on CPL's ongoing results of
operations or financial condition.


                      CONSTRUCTION PROGRAM

     CPL's capital expenditures for 1996-1998, including allowance for funds
used during construction ("AFUDC"), are estimated at $137 million, $157
million and $137 million, respectively.  CPL anticipates that the majority of
the funds required for its 1996-1998 capital expenditure program will be
provided from internal sources.  These estimates are subject to change due to
numerous factors, including load growth, escalation of construction costs,
changes in nuclear and environmental regulation, delays from regulatory
hearings, adequacy of rate relief and the availability of necessary external
capital.


                             EXPERTS

     The audited financial statements and schedules of CPL included in its
Annual Report on Form 10-K for the year ended December 31, 1995, which has
been incorporated herein by reference, have been examined by Arthur Andersen
LLP, independent public accountants, as indicated in their report dated
February 28, 1996 with respect thereto, which has been incorporated herein by
reference, in reliance upon the authority of said firm as experts in
accounting and auditing in giving said report.

herein, the requirements  contained herein shall be deemed to be amended to like
extent.  Any  amendment of the  requirements  contained  herein must satisfy the

               Indenture.

         Re:West Texas Utilities Company, Public
         Service Company of Oklahoma and Central
         Power and Light Company
         Certificate of Notification to
         Form U-1 Application-Declaration
         (File No. 70-8869)

Dear Sirs:

     We refer to the Form U-1  Application-Declaration  (File No. 70- 8869) (the
"Application-Declaration") under the Public Utility Holding Company Act of 1935,
as amended (the "1935 Act"), and the Certificate of Notification thereto,  filed
by West Texas Utilities  Company ("WTU"),  a Texas  corporation,  Public Service
Company of Oklahoma  ("PSO"),  an Oklahoma  corporation,  and Central  Power and
Light Company ("CPL",  and together with WTU and PSO, the "Companies"),  a Texas
corporation,  each, a wholly-owned  electric  utility  subsidiary of Central and
South West Corporation  ("CSW"), a Delaware corporation and a registered holding
company under the 1935 Act. The Certificate of Notification relates to the issue
and sale by Red  River  Authority  of Texas  (the  "Authority")  of  $63,300,000
aggregate  principal  amount of its Pollution  Control  Revenue  Refunding Bonds
(West Texas  Utilities  Company,  Public Service Company of Oklahoma and Central
Power and Light Company  Oklaunion  Project)  Series 1996, due June 1, 2020 (the
"Bonds").  In connection with the issuance of the Bonds,  the Companies  entered
into an Installment Payment Agreement (the "Installment Payment Agreement") with
the  Authority  which  obligated  the  Companies  to pay amounts  designed to be
sufficient to pay the principal of, premium,  if any, and interest on the Bonds.
In  connection   with  the   Application-Declaration   and  the  Certificate  of
Notification,  we have acted as special  counsel for the Companies  and, as such
counsel,  we are familiar with the corporate  proceedings taken by the Companies
in  connection  with the  issuance  and sale of the  Bonds as  described  in the
Application-Declaration and Certificate of Notification.

     In rendering the opinions expressed below, we have assumed, with respect to
all of the documents  referred to in this opinion letter,  that (except,  to the
extent set forth in the opinions expressed below, as to the Companies): (i) such
documents  have been duly  authorized  by, have been duly executed and delivered
by, and constitute legal, valid, binding and enforceable  obligations of, all of
the parties to such documents;  (ii) all signatories to such documents have been
duly  authorized;  and  (iii)  all of the  parties  to such  documents  are duly
organized and validly  existing and have the power and  authority  (corporate or
other) to execute, deliver and perform such documents.

     We have examined  originals,  or copies certified to our  satisfaction,  of
such  corporate  records of the  Companies,  certificates  of public  officials,
certificates  of  officers  and  representatives  of  the  Companies  and  other
documents  as we have deemed it necessary to require as a basis for the opinions
hereinafter  expressed.  In such  examination we have assumed the genuineness of
all  signatures  and  the  authenticity  of  all  documents  submitted  to us as
originals, the conformity with the originals of all documents submitted to us as
copies and the authenticity of such originals.  As to various  questions of fact
material to such opinions we have,  when relevant  facts were not  independently
established,  relied upon  certificates  by officers of the  Companies and other
appropriate persons and statements contained in the  Application-Declaration and
the Certificate of Notification.

     Based upon the foregoing,  and having regard to legal  considerations which
we deem relevant, we are of the opinion that:

     1. WTU and CPL are duly incorporated, validly existing and in good standing
under the laws of the State of Texas.

     2. PSO is duly  incorporated,  validly  existing and in good standing under
the laws of the State of Oklahoma.

     3. All state laws  applicable to the execution of the  Installment  Payment
Agreement by the Companies have been complied with.

     4. The Installment  Payment Agreement is a valid and binding  obligation of
the  Companies  enforceable  in  accordance  with  its  terms,  subject,  as  to
enforcement,  to  bankruptcy,  insolvency,  reorganization,  moratorium or other
similar laws of general  applicability  relating to or affecting the enforcement
of  creditors'  rights  generally  and to the effects of general  principles  of
