Dear Sirs:

      Public  Service Company of Oklahoma, an  Oklahoma
corporation  (the  "Company"), confirms  its  agreement
with  Smith  Barney  Inc.  and  Morgan  Stanley  &  Co.
Incorporated  (each  referred  to  as  an  "Agent"  and
collectively referred to as the "Agents") with  respect
to the issue and sale by the Company of its Medium-Term
Notes,  Series A, described herein (the "Notes").   The
Notes  are to be issued pursuant to an indenture  dated
as of February 1, 1996, as supplemented and as the same
may  from time to time be amended or supplemented  (the
"Indenture"), between the Company and Liberty Bank  and
Trust  Company  of  Tulsa,  National  Association,   as
trustee  (the "Trustee").  As of the date  hereof,  the
Company has authorized the issuance and sale of  up  to
$75,000,000 aggregate principal amount of Notes through
the Agents pursuant to the terms of this Agreement.  It
is  understood, however, that the Company may from time
to  time authorize the issuance of additional Notes and
that  such additional Notes may be sold through  or  to
the Agents pursuant to the terms of this Agreement, all
as though the issuance of such Notes were authorized as
of the date hereof.  Until the Release Date (as defined
in  the  Indenture), the Notes will be  secured  as  to
payment of principal and interest by one or more series
of  First  Mortgage Bonds (the "First Mortgage  Bonds")
issued,  pledged and delivered by the  Company  to  the
Trustee.   The  First  Mortgage Bonds  will  be  issued
pursuant  to the provisions of the Company's  Indenture
dated July 1, 1945, as supplemented and as the same may
from  time  to  time  be amended or  supplemented  (the
"First  Mortgage Indenture") to Liberty Bank and  Trust
Company of Tulsa, National Association, as Trustee (the
"First Mortgage Trustee").

     This Agreement provides both for the sale of Notes
by  the  Company directly to purchasers, in which  case
the  Agents  will  act  as agents  of  the  Company  in
soliciting  Note purchases, and (as may  from  time  to
time  be  agreed  to by the Company and the  applicable
Agent)   to  an  Agent  as  principal  for  resale   to
purchasers.

      The  Company  has filed with the  Securities  and
Exchange   Commission   (the  "SEC")   a   registration
statement   on  Form  S-3  (No.  333-00973)   for   the
registration of debt securities, including  the  Notes,
under the Securities Act of 1933, as amended (the "1933
Act"),  and the offering thereof from time to  time  in
accordance  with Rule 415 of the rules and  regulations
of   the  SEC  under  the  1933  Act  (the  "1933   Act
Regulations").   Such registration statement  has  been
declared  effective by the SEC and  the  Indenture  has
been  qualified under the Trust Indenture Act of  1939,
as   amended   (the  "1939  Act").   Such  registration
statement,   excluding  Form  T-1  (and   any   further
registration  statements which  may  be  filed  by  the
Company for the purpose of registering additional Notes
and   in  connection  with  which  this  Agreement   is
incorporated   by   reference)   and   the   prospectus
constituting   a  part  thereof,  and  any   prospectus
supplements  and  pricing supplements relating  to  the
Notes, including all documents incorporated therein  by
reference, as from time to time amended or supplemented
by  the  filing of documents pursuant to the Securities
Exchange  Act of 1934, as amended (the "1934 Act"),  or
the  1933  Act or otherwise, are referred to herein  as
the  "Registration  Statement"  and  the  "Prospectus",
respectively.

I.   Appointment as Agents.

     A.    Appointment of Agents.  Subject to the terms
and   conditions  stated  herein  and  subject  to  the
reservation by the Company of the right to  sell  Notes
directly on its own behalf, the Company hereby appoints
the  Agents as its agents for the purpose of soliciting
purchases  of the Notes from the Company by others  and
agrees  that, except as otherwise contemplated  herein,
whenever  the Company determines to sell Notes directly
to  an Agent as principal for resale to others, it will
enter   into  a  Terms  Agreement  (hereafter  defined)
relating to such sale in accordance with the provisions
of  Section 3(b) hereof.  The Agents are authorized  to
appoint  sub-agents or to engage the  services  of  any
other broker or dealer in connection with the offer  or
sale of the Notes.  The Company agrees that, during the
period  the  Agents are acting as the Company's  agents
hereunder,  the  Company will not  contact  or  solicit
potential  investors introduced to it by  an  Agent  to
purchase  the Notes.  The Company may appoint,  upon  3
business  days  prior  written notice  to  the  Agents,
additional  persons to serve as Agents  hereunder,  but
only  if each such additional person agrees to be bound
by all of the terms of this Agreement as an Agent.

     B.    Reasonable Best Efforts Solicitations; Right
to  Reject  Offers.  Upon receipt of instructions  from
the  Company,  each Agent will use its reasonable  best
efforts  to solicit purchases of such principal  amount
of  the Notes as the Company and such Agent shall agree
upon  from  time  to  time  during  the  term  of  this
Agreement,  it being understood that the Company  shall
not  approve the solicitation of purchases of Notes  in
excess  of the amount which shall be authorized by  the
Company from time to time or in excess of the principal
amount of Notes registered pursuant to the Registration
Statement.  The Agents will have no responsibility  for
maintaining  records  with  respect  to  the  aggregate
principal   amount  of  Notes  sold,  or  of  otherwise
monitoring the availability of Notes for sale under the
Registration Statement.  Each Agent will communicate to
the  Company,  orally  or  in writing,  each  offer  to
purchase  Notes,  other than those offers  rejected  by
such  Agent.  Each Agent shall have the right,  in  its
discretion reasonably exercised, to reject any proposed
purchase of Notes, as a whole or in part, and any  such
rejection shall not be deemed a breach of such  Agent's
agreement contained herein.  The Company may accept, in
its discretion reasonably exercised, or reject, and any
such  rejection  shall not be deemed a  breach  of  the
Company's  agreement  contained  herein,  any  proposed
purchase of the Notes, in whole or in part.

     C.         Solicitations  as Agent;  Purchases  as
Principal.   In soliciting purchases of  the  Notes  on
behalf  of the Company, the Agents shall act solely  as
agents for the Company and not as principal.  An  agent
shall  make  reasonable  best  efforts  to  assist  the
Company  in  obtaining performance  by  each  purchaser
whose  offer  to purchase Notes has been  solicited  by
such  Agent  and accepted by the Company.   The  Agents
shall  not  have  any liability to the Company  in  the
event  any  such  purchase is not consummated  for  any
reason.   An  Agent  shall not have any  obligation  to
purchase Notes from the Company as principal, but  each
Agent  may agree with the Company from time to time  to
purchase  Notes  as principal.  Any  such  purchase  of
Notes  by  an Agent as principal shall be made pursuant
to  a  Terms Agreement in accordance with Section  3(b)
hereof.

     D.     Reliance.  The Company and each Agent agree
that  any  Notes  the  placement of  which  such  Agent
arranges  shall be placed by such Agent, and any  Notes
purchased by such Agent shall be purchased, in reliance
on   the  representations,  warranties,  covenants  and
agreements of the Company contained herein and  on  the
terms and conditions and in the manner provided herein.

     E.         Administrative Procedures.   Procedural
details relating to the issue and delivery of the Notes
and  the  payment  therefor, unless an  Agent  and  the
Company shall otherwise agree, shall be as set forth in
the  Administrative Procedures attached hereto as Annex
I  as  it  may be amended from time to time by  written
agreement  between  the Agents  and  the  Company  (the
"Administrative  Procedures").  The provisions  of  the
Administrative   Procedures   shall   apply   to    all
transactions  contemplated hereunder other  than  those
made pursuant to a Terms Agreement.  Each Agent and the
Company   shall  perform  the  respective  duties   and
obligations  specifically provided to be  performed  by
each of them in the Administrative Procedures.

SECTION 2.     Representations and Warranties.

      a     The Company represents and warrants to each
Agent  as  of the date hereof, as of the date  of  each
acceptance by the Company of an offer for the  purchase
of  Notes (whether through an Agent as agent or  to  an
Agent as principal), as of the date of each delivery of
Notes  (whether through such Agent as agent or  to  the
Agent as principal) (the date of each such delivery  to
an  Agent as principal being hereinafter referred to as
a  "Settlement  Date"), and as of  any  time  that  the
Registration  Statement  or  the  Prospectus  shall  be
amended or supplemented (other than by an amendment  or
supplement  providing  solely  for  a  change  in   the
interest rates of Notes or similar changes) or there is
filed  with  the  SEC  any  document  incorporated   by
reference  into the Prospectus (other than any  Current
Report on Form 8-K relating exclusively to the issuance
of  debt  securities under the Registration  Statement,
unless the Agents shall otherwise specify) (each of the
times  referenced above being referred to herein  as  a
"Representation Date") as follows:

           i. Due Incorporation and Qualification.  The
     Company  has been duly incorporated and is validly
     existing  as a corporation in good standing  under
     the laws of the State of   Oklahoma with corporate
     power  and authority to own its properties and  to
     conduct   its   business  as  described   in   the
     Prospectus; and the Company is duly qualified as a
     foreign corporation to transact business and is in
     good  standing in each jurisdiction in which  such
     qualification is required, whether  by  reason  of
     the  ownership  or  leasing  of  property  or  the
     conduct  of business, except where the failure  to
     so qualify or be in good standing would not result
     in (A) a material adverse change in the condition,
     financial or otherwise, or in the earnings of  the
     Company  and  its subsidiaries considered  as  one
     enterprise or (B) a material adverse change in its
     prospective  financial  condition  or  results  of
     operations, in either case whether or not  arising
     in the ordinary course of business.

           ii.   Subsidiaries.  Each subsidiary of  the
     Company which is a significant subsidiary (each  a
     "Significant Subsidiary") as defined in  Rule  405
     of  Regulation  C of the 1933 Act Regulations  has
     been duly incorporated and is validly existing  as
     a  corporation in good standing under the laws  of
     the   jurisdiction   of  its  incorporation,   has
     corporate   power  and  authority   to   own   its
     properties  and conduct its business as  described
     in  the  Prospectus  and is duly  qualified  as  a
     foreign corporation to transact business and is in
     good  standing in each jurisdiction in which  such
     qualification is required, whether  by  reason  of
     the  ownership  or  leasing  of  property  or  the
     conduct  of business, except where the failure  to
     so qualify or be in good standing would not result
     in (A) a material adverse change in the condition,
     financial  or  otherwise, or the earnings  of  the
     Company  and  its subsidiaries considered  as  one
     enterprise or (B) a material adverse change in the
     Company's   prospective  financial  condition   or
     results  of operations, in either case whether  or
     not  arising  in the ordinary course of  business;
     and  all  of  the  issued and outstanding  capital
     stock of each Significant Subsidiary has been duly
     authorized and validly issued, is fully  paid  and
     non-assessable   and,   except   for    directors'
     qualifying  shares,  is  owned  by  the   Company,
     directly  or through subsidiaries, free and  clear
     of  any security interest, mortgage, pledge, lien,
     encumbrance, claim or equity.

           iii.  Registration Statement and Prospectus.
     At  the  time  the  Registration Statement  became
     effective, the Registration Statement complied, and as
     of the applicable Representation Date will comply, in
     all material respects with the requirements of the 1933
     Act and the 1933 Act Regulations and the 1939 Act and
     the  rules  and regulations of the SEC promulgated
     thereunder.  The Registration Statement, at the time it
     became effective, did not, and at each time thereafter
     at which any amendment to the Registration Statement
     becomes effective or any Annual Report on Form 10-K is
     filed  by the Company with the SEC and as of  each
     Representation Date, will not, contain  an  untrue
     statement  of a material fact or omit to  state  a
     material  fact  required to be stated  therein  or
     necessary  to  make  the  statements  therein  not
     misleading.  The Prospectus, as of the date hereof does
     not,  and as of each Representation Date will not,
     contain an untrue statement of a material fact or omit
     to state a material fact necessary in order to make the
     statements therein, in the light of the circumstances
     under which they were made, not misleading; provided,
     however, that the representations and warranties in
     this subsection shall not apply to statements in or
     omissions from the Registration Statement or Prospectus
     resulting from the failure of any of the Agents to
     furnish the Company with information pertaining to such
     Agents and the sale of the Notes required to complete
     the  Registration Statement or the Prospectus,  to
     statements in the Form T-1 filed by the Trustee and
     First Mortgage Trustee as exhibits to the Registration
     Statement or to statements in or omissions from the
     Prospectus made in reliance upon and in conformity with
     information furnished to the Company in writing by the
     Agents expressly for use in the Registration Statement
     or Prospectus.

           iv.   Incorporated Documents.  The documents
     incorporated by reference in the Prospectus, at the
     time they were or hereafter are filed with the SEC,
     complied or when so filed will comply, as the case may
     be, in all material respects with the requirements of
     the 1934 Act and the rules and regulations promulgated
     thereunder (the "1934 Act Regulations"), and, when read
     together  and  with the other information  in  the
     Prospectus, did not and will not contain an untrue
     statement  of a material fact or omit to  state  a
     material  fact  required to be stated  therein  or
     necessary in order to make the statements therein, in
     the light of the circumstances under which they were or
     are made, not misleading.


           v.  Accountants.  The accountants who certified
     the financial statements included or incorporated by
     reference in the Prospectus are independent public
     accountants within the meaning of the 1933 Act and the
     1933 Act Regulations.

           vi.  [Intentionally Left Blank].

           vii.   Authorization and  Validity  of  this
     Agreement, the Indenture and the Notes.  This Agreement
     has been duly authorized, executed and delivered by the
     Company; the Indenture has been duly authorized and
     constitutes a valid and binding obligation of  the
     Company enforceable in accordance with its  terms,
     except  as  enforcement thereof may be limited  by
     bankruptcy, insolvency, reorganization, moratorium or
     other laws relating to or affecting enforcement of
     creditors'  rights generally or by general  equity
     principles;  the Notes have been duly and  validly
     authorized for issuance, offer and sale pursuant to
     this Agreement and, when issued, authenticated and
     delivered pursuant to the provisions of this Agreement
     and the Indenture against payment of the consideration
     therefor specified in the Prospectus or pursuant to any
     Terms Agreement, the Notes will constitute valid and
     legally binding obligations of the Company enforceable
     in accordance with their terms, except as enforcement
     thereof  may be limited by bankruptcy, insolvency,
     reorganization, moratorium or similar laws relating to
     or affecting enforcement of creditors' rights generally
     or by general equity principles; the Notes and the
     Indenture will be substantially in the form heretofore
     delivered to the Agents and conform in all material
     respects to the statements relating thereto contained
     in the Prospectus; and the Notes will be entitled to
     the benefits provided by the Indenture.

           viii.    Material   Changes   or   Material
     Transactions.  Since the respective dates as of which
     information is given in the Registration Statement and
     the  Prospectus, except as may otherwise be stated
     therein  or  contemplated thereby  (including  the
     financial statements and notes thereto included or
     incorporated  by  reference  in  the  Registration
     Statement) and except as the Company may have furnished
     supplemental information to each prospective Agent as
     to matters to be reflected in the Prospectus, there has
     been no (A) material adverse change in the condition,
     financial or otherwise, or in the earnings of  the
     Company  and  its subsidiaries considered  as  one
     enterprise or (B) adverse development concerning the
     Company's business or assets which would result in a
     material adverse change in its prospective financial
     condition or results of operations, in either case
     whether  or not arising in the ordinary course  of
     business.

           ix.   No Defaults.  Neither the Company  nor
     any of its Significant Subsidiaries is in violation of
     its  charter  or in default in the performance  or
     observance of any obligation, agreement, covenant or
     condition  contained  in  any  material  contract,
     indenture, mortgage, loan agreement, note, lease or
     other instrument to which it is a party or by which it
     or any of them or their properties is bound that would
     result  in  (A) a material adverse change  in  the
     condition, financial or otherwise, or in the earnings
     of the Company and its subsidiaries considered as one
     enterprise or (B) a material adverse change in its
     prospective  financial  condition  or  results  of
     operations, in either case whether or not arising in
     the ordinary course of business; or materially and
     adversely affect the performance by the Company of the
     obligations under this Agreement or consummation of the
     transaction  contemplated by this  Agreement;  the
     execution and delivery of this Agreement  and  the
     Indenture and the consummation of the transactions
     contemplated herein, therein and pursuant  to  any
     applicable Terms Agreement have been duly authorized by
     all necessary corporate action and will not conflict
     with or constitute a breach of, or default under, or
     result in the creation or imposition of any  lien,
     charge or encumbrance upon any property or assets of
     the Company or any of its Significant Subsidiaries
     pursuant  to,  any  material contract,  indenture,
     mortgage,  loan  agreement, note, lease  or  other
     instrument  to  which the Company or  any  of  its
     Significant Subsidiaries is a party or by which it or
     any  of  them may be bound or to which any of  the
     property  or  assets of the Company  or  any  such
     subsidiary is subject, nor will such action result in
     any violation of the provisions of the charter  or
     by-laws  of the Company or any law, administrative
     regulation or administrative or court order applicable
     to the Company or any such subsidiary.


           x.    Authorization,  Approval  or  Consent
     Required.    The   Company  is  subject   to   the
     jurisdiction    of   the   Oklahoma    Corporation
     Commission ("OCC") which is vested with powers  of
     supervision,  regulation and control over  various
     matters including the issuance of securities.   No
     authorization, approval or consent of any court or
     governmental  authority or agency is necessary  in
     connection with the sale of the Notes or the First
     Mortgage  Bonds  hereunder,  including  under  the
     Public  Utility Holding Company Act  of  1935,  as
     amended  (the  "1935 Act"), except  (i)  for  such
     orders as are required by the OCC authorizing  the
     issuance  and  sale  of the Notes  and  the  First
     Mortgage  Bonds  on  terms  consistent  with  this
     Agreement, the Administrative Procedures  and  any
     applicable Terms Agreement, which orders have been
     obtained,  are in full force and effect  and  have
     been  heretofore delivered to the Agents, and (ii)
     as otherwise may be required under the 1933 Act or
     the  1933  Act Regulations or state securities  or
     Blue Sky laws.

           xi.  Title to Property.  The Company and its
     subsidiaries have good and marketable title in fee
     simple (or its equivalent under applicable law) to all
     real property and good and marketable title to all
     personal property owned by them which is material to
     the business of the Company and its subsidiaries, in
     each case free and clear of all liens, encumbrances and
     defects except such as are described in the Prospectus
     or such as do not materially affect the value of such
     property and do not interfere with the use made and
     proposed to be made of such property by the Company and
     its subsidiaries; and any real property and buildings
     held under lease by the Company and its subsidiaries
     are  held  by  them  under valid,  subsisting  and
     enforceable leases with such exceptions as are not
     material and do not interfere with the use made and
     proposed to be made of such property and buildings by
     the Company and its subsidiaries.


           xii.    Environmental  and  Other  Matters.
     Except as set forth in the Registration Statement,
     neither  the Company nor its subsidiaries (in  the
     case   of   matters   relating  to   environmental
     protection,  occupational safety  and  health  and
     equal  employment opportunity, to the best of  its
     knowledge)  (a)  is  in  violation  of  any  laws,
     ordinances, governmental rules and regulations  to
     which  it  is subject or (b) has failed to  obtain
     any   licenses,  permits,  franchises   or   other
     governmental  authorizations,  necessary  to   the
     ownership of its property or to the conduct of its
     business,  which  violation  or  such  failure  to
     obtain  would  materially  adversely  affect   the
     business,  business prospects, profits, properties
     or  condition  (financial  or  otherwise)  of  the
     Company  and  its subsidiaries considered  as  one
     enterprise.


      b.   Additional Certifications.  Any  certificate
signed  by  any director or officer of the Company  and
delivered to the Agents or to counsel for the Agents in
connection  with an offering of Notes or  the  sale  of
Notes  to  the  agent as principal shall  be  deemed  a
representation  and  warranty by  the  Company  to  the
Agents as to the matters covered thereby on the date of
such  certificate (unless otherwise specified  in  such
certificate) and at each Representation Date subsequent
thereto.

SECTION 3.  Solicitations as Agent; Purchases as Principal.

      a.   Solicitations as Agent.  On the basis of the
representations  and warranties herein  contained,  but
subject  to the terms and conditions herein set  forth,
each Agent agrees, as the agent of the Company, to  use
its  reasonable  best  efforts to  solicit  offers  and
receive offers to purchase the Notes upon the terms and
conditions set forth herein and in the Prospectus.

           The  Company reserves the right, in its sole
discretion, to suspend solicitation of purchases of the
Notes  through  an Agent, as agent, commencing  at  any
time for any period of time or permanently.  As soon as
practicable,  but  in  any  case  not  later  than  one
business  day  after receipt of instructions  from  the
Company, such Agent will forthwith suspend solicitation
of  purchases from the Company until such time  as  the
Company  has  advised such Agent that such solicitation
may be resumed.

           The  Company  agrees to  pay  each  Agent  a
commission,  in the form of a discount,  equal  to  the
applicable percentage of the principal amount  of  each
Note  sold by the Company as a result of a solicitation
made  by  such Agent as set forth in Schedule A hereto.
An  Agent  may  reallot any portion of  the  commission
payable  pursuant  hereto to dealers or  purchasers  in
connection with the offer and sale of any Notes.

           The  purchase price, interest rate, maturity
date  and other terms of the Notes shall be agreed upon
by  the  Company  and the Agents and  set  forth  in  a
pricing  supplement to the Prospectus  to  be  prepared
following  each acceptance by the Company of  an  offer
for  the purchase of Notes.  Except as may be otherwise
provided  in  such  supplement to the  Prospectus,  the
Notes  will  be issued in denominations of $100,000  or
any  larger  amount  that is an  integral  multiple  of
$1,000.  All Notes sold through an Agent as agent  will
be  sold  at  100%  of  their principal  amount  unless
otherwise agreed to by the Company and such Agent.

     b.  Purchases as Principal.  Each sale of Notes to
an  Agent as principal shall be made in accordance with
the  terms contained herein and (unless the Company and
such  Agent  shall  otherwise  agree)  pursuant  to   a
separate agreement which will provide for the  sale  of
such  Notes to, and the purchase and reoffering thereof
by,  such  Agent.  Each such separate agreement  (which
may  be  an oral agreement) between such Agent and  the
Company  is  herein referred to as a "Terms Agreement".
Unless  the context otherwise requires, each  reference
contained herein to "this Agreement" shall be deemed to
include  any  applicable Terms  Agreement  between  the
Company  and  the  applicable Agent.  Each  such  Terms
Agreement,  whether oral or in writing, shall  be  with
respect  to  such  information (as  applicable)  as  is
specified  in Exhibit A hereto.  An Agent's  commitment
to  purchase Notes as principal pursuant to  any  Terms
Agreement  or  otherwise shall be deemed to  have  been
made on the basis of the representations and warranties
of the Company herein contained and shall be subject to
the  terms and conditions herein set forth.  Each Terms
Agreement shall specify the principal amount  of  Notes
to  be  purchased by such Agent pursuant  thereto,  the
price  to be paid to the Company for such Notes (which,
if not so specified in a Terms Agreement, shall be at a
discount  equivalent to the applicable  commission  set
forth  in  Schedule A hereto), the time  and  place  of
delivery  of and payment for such Notes, any provisions
relating to rights of, and default by purchasers acting
together  with  such  Agent in the  reoffering  of  the
Notes,  and  such  other provisions (including  further
terms  of  the  Notes) as may be mutually agreed  upon.
Each  Agent  may utilize a selling or dealer  group  in
connection  with  the  resale of the  Notes  purchased.
Such   Terms   Agreement   shall   also   specify   the
requirements for the officers' certificate, opinions of
counsel  and comfort letter pursuant to Sections  7(b),
7(c) and 7(d) hereof.

SECTION 4.  Covenants of the Company.

     The Company covenants with each Agent as follows:

     A.     Notice of Certain Events.  The Company will
notify  the Agents immediately (i) of the effectiveness
of any amendment to the Registration Statement, (ii) of
the transmittal to the SEC for filing of any supplement
to the Prospectus, (iii) of the receipt of any comments
from the SEC with respect to the Registration Statement
or  the Prospectus, (iv) of any request by the SEC  for
any  amendment  to  the Registration Statement  or  any
amendment  or  supplement  to  the  Prospectus  or  for
additional information, and (v) of the issuance by  the
SEC  of any stop order suspending the effectiveness  of
the  Registration  Statement or the initiation  of  any
proceedings  for that purpose.  The Company  will  make
every reasonable effort to prevent the issuance of  any
stop  order and, if any stop order is issued, to obtain
the lifting thereof at the earliest possible moment.

     B.        Notice of Certain Proposed Filings.  The
Company will give the Agents notice of its intention to
file  or  prepare any additional registration statement
with  respect to the registration of additional  Notes,
any  amendment  to  the Registration Statement  or  any
amendment  or supplement to the Prospectus (other  than
an  amendment  or  supplement providing  solely  for  a
change in the interest rates of Notes or the filing  of
reports  under the 1934 Act), whether by the filing  of
documents  pursuant to the 1933 Act  or  otherwise  and
will  furnish  the  Agents  with  copies  of  any  such
amendment or supplement or other documents proposed  to
be  filed  or prepared a reasonable time in advance  of
such  proposed filing or preparation, as the  case  may
be,  and will not file any such amendment or supplement
or  other  documents in a form to which the  Agents  or
counsel for the Agents shall reasonably object.

     C.    Copies of the Registration Statement and the
Prospectus.  The Company will deliver to the Agents  as
many  signed  and conformed copies of the  Registration
Statement  (as originally filed) and of each  amendment
thereto   (including   exhibits  filed   therewith   or
incorporated   by  reference  therein   and   documents
incorporated  by  reference in the Prospectus)  as  the
Agents  may  reasonably  request.   The  Company   will
furnish  to the Agents as many copies of the Prospectus
(as  amended  or  supplemented)  as  the  Agents  shall
reasonably  request so long as the Agents are  required
to  deliver  a Prospectus in connection with  sales  or
solicitations of offers to purchase the Notes.

     D.        Preparation of Pricing Supplements.  The
Company will prepare, with respect to any Notes  to  be
sold   through  or  to  any  Agent  pursuant  to   this
Agreement,  a Pricing Supplement with respect  to  such
Notes  in a form previously approved by such Agent  and
will   file   such  Pricing  Supplement   pursuant   to
Rule 424(b) under the 1933 Act not later than the close
of  business of the SEC on the fifth business day after
the  date  on  which such Pricing Supplement  is  first
used.


     E.    Revisions of Prospectus -- Material Changes.
Except as otherwise provided in subsection (l) of  this
Section,  if  at  any  time during  the  term  of  this
Agreement any event shall occur or condition exist as a
result  of  which it is necessary, in  the   reasonable
opinion  of counsel for the Agents (and concurred  with
by  counsel of the Company) or counsel for the Company,
to  further amend or supplement the Prospectus in order
that   the  Prospectus  will  not  include  an   untrue
statement  of  a  material fact or omit  to  state  any
material fact necessary in order to make the statements
therein   not   misleading  in   the   light   of   the
circumstances  existing at the time the  Prospectus  is
delivered  to a purchaser, or if it shall be necessary,
in  the  reasonable opinion of counsel for  the  Agents
(and  concurred  with by counsel  of  the  Company)  or
counsel  for  the  Company to amend or  supplement  the
Registration Statement or the Prospectus  in  order  to
comply  with the requirements of the 1933  Act  or  the
1933  Act Regulations, immediate notice shall be given,
and  confirmed in writing, to the Agents to  cease  the
solicitation  of offers to purchase the  Notes  in  the
Agents'  capacity as agents and to cease sales  of  any
Notes the Agents may then own as principal pursuant  to
a  Terms  Agreement,  and  the  Company  will  promptly
prepare  and  file  with  the  SEC  such  amendment  or
supplement, whether by filing documents pursuant to the
1934  Act,  the  1933  Act  or  otherwise,  as  may  be
necessary to correct such untrue statement or  omission
or  to  make  the Registration Statement and Prospectus
comply with such requirements.

     F.      Prospectus Revisions -- Periodic Financial
Information.    Except   as   otherwise   provided   in
subsection (l) of this Section, on or prior to the date
on  which there shall be released to the general public
in  the  form  of  a  press release  interim  financial
statement  information  related  to  the  Company  with
respect  to  each  of the first three quarters  of  any
fiscal   year   or   preliminary  financial   statement
information  with  respect  to  any  fiscal  year,  the
Company  shall furnish such information to the  Agents,
confirmed in writing, and shall cause the Prospectus to
be amended or supplemented to include or incorporate by
reference  financial information with  respect  thereto
and corresponding information for the comparable period
of  the  preceding fiscal year, as well as  such  other
information and explanations as shall be necessary  for
an understanding thereof or as shall be required by the
1933 Act or the 1933 Act Regulations.

     G.       Prospectus Revisions -- Audited Financial
Information.    Except   as   otherwise   provided   in
subsection (l) of this Section, on or prior to the date
on  which there shall be released to the general public
in  the  form  of a press release financial information
included  in  or  derived from  the  audited  financial
statements  of  the  Company for the  preceding  fiscal
year,   the   Company  shall  cause  the   Registration
Statement and the Prospectus to be amended, whether  by
the  filing of documents pursuant to the 1934 Act,  the
1933  Act  or  otherwise, to include or incorporate  by
reference  such  audited financial statements  and  the
report  or  reports, and consent or  consents  to  such
inclusion  or  incorporation  by  reference,   of   the
independent accountants with respect thereto,  as  well
as such other information  and  explanations  as  shall
be  necessary  for  an  understanding of such financial
statements or as shall be required by the 1933  Act  or
the 1933 Act Regulations.

     H.     Earnings Statements.  The Company will make
generally available to its security holders as soon  as
practicable,  but in any event not later than  90  days
after  (i)  the  effective  date  of  the  Registration
Statement,  (ii)  the  effective  date  of  each  post-
effective amendment to the Registration Statement,  and
(iii)  the date of each filing by the Company with  the
SEC   of  an  Annual  Report  on  Form  10-K  that   is
incorporated   by   reference   in   the   Registration

subsidiaries (which need not be audited) complying with
Section  11(a) of the Act and the rules and regulations
of  the SEC thereunder (including, at the option of the
Company, Rule 158).

     I.      Blue Sky Qualifications.  The Company will
endeavor,  in cooperation with the Agents,  to  qualify
the  Notes  for offering and sale under the  applicable
securities  laws of such states and other jurisdictions
of the United States as the Agents may designate and as
approved  by  the  Company,  and  will  maintain   such
qualifications in effect for as long as may be required
for  the  distribution  of  the  Notes  and  the  First
Mortgage  Bonds;  provided, however, that  the  Company
shall  not be obligated to file any general consent  to
service   of  process  or  to  qualify  as  a   foreign
corporation in any jurisdiction in which it is  not  so
qualified.   The Company will file such statements  and
reports  as  may  be  required  by  the  laws  of  each
jurisdiction  in which the Notes or the First  Mortgage
Bonds  have  been  qualified as  above  provided.   The
Company  will promptly advise the Agents of the receipt
by  the Company of any notification with respect to the
suspension  of the qualification of the  Notes  or  the
First  Mortgage  Bonds for sale in any  such  state  or
jurisdiction  or the initiating or threatening  of  any
preceding for such purpose.

     J.      1934 Act Filings.  The Company, during the
period  when the Prospectus is required to be delivered
under  the  1933 Act, will file promptly all  documents
required  to be filed with the SEC pursuant to Sections
13(a), 13(c), 14 or 15(d) of the 1934 Act.

     K.   Stand-Off Agreement.  If required pursuant to
the terms of a Terms Agreement, between the date of any
Terms Agreement and the Settlement Date with respect to
such Terms Agreement, the Company will not, without the
applicable  Agent's prior consent, offer  or  sell,  or
enter  into  any agreement to sell, any debt securities
of  the  Company (other than the Notes that are  to  be
sold  pursuant  to such Terms Agreement,  notes  issued
pursuant   to  a  credit  facility  or  other   similar
agreement  and commercial paper in the ordinary  course
of business).

     L.         Suspension of Certain Obligations.  The
Company  shall  not  be required  to  comply  with  the
provisions  of  subsections (e), (f)  or  (g)  of  this
Section  during  any period from the  time  the  Agents
shall  have suspended solicitation of purchases of  the
Notes in their capacity as agents pursuant to a request
from the Company to the time the Company shall determine
that solicitation of  purchases  of  the  Notes  should
be resumed or shall subsequently enter into a new Terms
Agreement with either or both of the Agents.

     M.   Condition to Agency Transactions.  Any person
who  has agreed to purchase Notes as the result  of  an
offer to purchase solicited by an Agent shall have  the
right to refuse to purchase and pay for such Notes  if,
on  the  related settlement date fixed pursuant to  the
Administrative  Procedures, (i) there has  been,  since
the  date  on which such person agreed to purchase  the
Notes  (the  "Trade  Date"), (A) any  material  adverse
change in the condition, financial or  otherwise, or in
the  earnings  of  the  Company  and  its  subsidiaries
considered  as  one  enterprise  or  (B)  any   adverse
development concerning the Company's business or assets
which would result in a material adverse change in  the
prospective   financial   condition   or   results   of
operations, in either case, whether or not  arising  in
the  ordinary course of business, or (ii)  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 purchaser,
impracticable  to purchase the Notes, or (iii)  trading
in any securities of the Company  has been suspended by
the  SEC  or  a  national securities  exchange,  or  if
trading generally on the New York Stock Exchange  shall
have  been  suspended, or any limitation on prices  for
such trading or any restrictions on the distribution of
securities has been promulgated, by said exchange or by
order  of  the  SEC  or any other Federal  governmental
authority,  or  if  a general banking moratorium  shall
have  been  declared  by either  Federal  or  New  York
authorities,  or  (iv)  the  rating  assigned  by   any
nationally recognized securities rating agency  to  any
debt  securities of the Company as of  the  Trade  Date
shall have been lowered since that date.

           The  obligations  of each Agent  to  solicit
offers  to purchase the Notes as agent of the  Company,

Agent  to  purchase Notes pursuant to a Terms Agreement
or  otherwise  will be subject to the accuracy  of  the

Company herein and to the accuracy of the statements of
the   Company's   officers  made  in  any   certificate
furnished  pursuant to the provisions  hereof,  to  the

     The  opinion  of Sidley & Austin, counsel  to  the

President or any Vice President and the chief financial
officer,    chief   accounting   officer,    treasurer,

the  date  hereof,  to the effect that  (i)  since  the
respective  dates as of which information is  given  in
the  Registration Statement and the Prospectus or since
the  date of any applicable Terms Agreement, there  has
been  no  (A) material adverse change in the condition,
financial  or  otherwise, or in  the  earnings  of  the
Company   or  (B)  adverse development  concerning  the
Company's  business or assets which would result  in  a
material  adverse  change in its prospective  financial

and   notes   thereto   contained   in   any   document
incorporated by reference therein), (ii) the  order  of
the  OCC referred to in subsection (x) of Section 2  of

initiated or threatened by the SEC.

     C.         Comfort Letter. On or prior to the date
hereof,  the  Agents  shall have received  from  Arthur
Anderson   LLP  a  letter  confirming  that  they   are
independent  public  accountants with  respect  to  the
Company  within  the meaning of the 1933  Act  and  the
applicable  published rules and regulations  thereunder
and  that  the  answer to Item 10 of  the  Registration
Statement is correct insofar as it relates to them  and
stating  in  effect  (1)  that  in  their  opinion  the
financial  statements  and  schedules  of  the  Company
incorporated                                         by
reference    in   the   Registration   Statement    and
Prospectus  and which are stated therein to  have  been
certified or audited by them, comply as to form, in all
material   respects,  with  the  applicable  accounting
requirements  of  the 1933 Act and the published  rules
and  regulations thereunder; (2) that nothing has  come
to   their  attention  which  causes  them  to  believe
(A)  that any unaudited dollar amounts or ratios  which
may  appear  in  the  Registration  Statement  and  the
Prospectus  under  the caption "The Company"  were  not
determined  on  a  basis substantially consistent  with
that  of  the  corresponding  amounts  in  the  audited
financial statements incorporated by reference  in  the
Registration Statement and the Prospectus; (B) that any
unaudited condensed financial statements of the Company
included  in  any of the Company's Form 10-Q  Quarterly
Reports, which may be incorporated by reference in  the
Registration  Statement  and  the  Prospectus,  do  not
comply  as  to form in all material respects  with  the
applicable accounting requirements of the 1934 Act  and
the   applicable   published  rules   and   regulations
thereunder,  or that material modifications  should  be
made to such unaudited financial statements for them to
be  in  conformity  with generally accepted  accounting
principles; or (C) that, except in all instances as set
forth or contemplated in the Registration Statement  or
the Prospectus, (i) at the date of the latest available
unaudited financial statements of the Company  read  by
them  and  at  a  subsequent date, not more  than  five
business  days before the date hereof, there  has  been
any  change in the capital stock or long-term  debt  of
the  Company,  as compared with amounts  shown  in  the
latest  balance  sheet  of  the  Company  included   or
incorporated by reference in the Registration Statement
and  the  Prospectus,  except  for  normally  scheduled
reductions  in  the  Company's  long-term   debt,   and
(ii)  for  the  period  from the  date  of  the  latest
financial   statements  included  or  incorporated   by
reference  in the Prospectus to the date of the  latest
available interim financial statements read by them and
to  the aforementioned date not more than five business
days  prior to the Closing Date there was any decrease,
as  compared  with  the  corresponding  period  in  the
preceding   twelve  month  period,  in  the   Company's
operating  revenues, operating income or net income  or
(iii)  there was any decrease in the ratio of  earnings
to  fixed charges for the twelve months ended the  date
of  such  latest available interim financial statements
as  compared to such ratio for the twelve months  ended
the date of the latest financial statements included or
incorporated by reference in the Prospectus, except  as
set  forth  in  such letter, in which latter  case  the
letter  shall be accompanied by an explanation  by  the
Company  as  to  the significance thereof  unless  such
explanation is not deemed necessary by the Agents;  and
(3)  that  they  have compared certain  dollar  amounts
designated  by  the  Company  and  disclosed   in   the
Registration Statement and Prospectus with such  dollar
amounts contained in the general accounting records  of
the  Company or derived directly from such  records  by
analysis  or  computation, and have found  such  dollar
amounts  to  be  in  agreement  therewith,  except   as
otherwise specified in such letter in which latter case
the  letter  shall be accompanied by an explanation  by
the  Company as to the significance thereof unless such
explanation is not deemed necessary by the Agents.


                The  form  of letter shall reflect  the
inclusion of any financial information filed subsequent
to   the  date  of  the  Registration  Statement,   the
incorporation  by  reference of any subsequently  filed
Annual Report on Form 10-K or Quarterly Report on  Form
10-Q  and/or  the  inclusion in the Prospectus  of  any
statistical or financial information.

               Subsequent to the respective dates as of
which   information  is  given  in   the   Registration
Statement and the Prospectus, there shall not have been
any change or decrease specified in the letter required
by  this  subsection (c) which is,  in  the  reasonable
judgment of the Agents, so material and adverse  as  to
make it impractical or inadvisable to proceed with  the
offering  or  the delivery of the Notes as contemplated
by the Registration Statement and the Prospectus.


     D.   First Mortgage Bonds.  The Company shall have
delivered  to the Trustee, as security for the  payment
of  the  principal  and interest on  the  Notes,  First
Mortgage  Bonds in the same aggregate principal  amount
and  with  the  same  stated rate, maturity  dates  and
redemption  provisions as the Notes they  secure.   The
First  Mortgage  Bonds will be issued  by  the  Company
under  its  Indenture dated July 1,  1945  between  the
Company  and Liberty Bank and Trust Company  of  Tulsa,
National   Association,  as  heretofore   amended   and
supplemented   and  as  to  be  further   amended   and
supplemented by a supplemental indenture or  supplement
indentures  creating  the series  in  which  the  First
Mortgage Bonds are to be issued.

     E.     Other Documents.  On the date hereof and on
each  Settlement  Date with respect to  any  applicable
Terms Agreement, counsel to the Agents shall have  been
furnished  with  such documents and  opinions  as  such
counsel  may  reasonably require  for  the  purpose  of
enabling  such  counsel to pass upon the  issuance  and
sale  of  Notes  as  herein  contemplated  and  related
proceedings,  or in order to evidence the accuracy  and
completeness   of   any  of  the  representations   and
warranties,   or  the  fulfillment  of   any   of   the
conditions, herein contained; and all proceedings taken
by the Company in connection with the issuance and sale
of  Notes  as  herein contemplated shall be  reasonably
satisfactory in form and substance to the Agents and to
counsel to the Agents.

     If any condition specified in this Section 5 shall
not have been (i) fulfilled when and as required to  be
fulfilled  or  (ii) waived by the applicable  Agent  or
Agents,  this  Agreement (or,  at  the  option  of  the
applicable  Agent, any applicable Terms Agreement)  may
be terminated by the Agents by notice to the Company at
any  time  and  any such termination shall  be  without
liability of any party to any other party, except  that
the   covenant  regarding  provision  of  an   earnings
statement  set  forth  in  Section  4(h)  hereof,   the
provisions   concerning  payment  of   expenses   under
Section  10  hereof,  the  indemnity  and  contribution
agreement  set  forth in Sections 8 and 9  hereof,  the
provisions  concerning the representations,  warranties
and agreements to survive delivery of Section 11 hereof
and the provisions set forth under "Parties" of Section
15 hereof shall remain in effect.

SECTION  6.   Delivery of and Payment  for  Notes  Sold
              through the Agents.

      Delivery of Notes sold through an Agent as  agent
shall  be  made  by the Company to such Agent  for  the
account  of any purchaser only against payment therefor
in  immediately available Federal funds.  In the  event
that  a  purchaser shall fail either to accept delivery
of  or to make payment for a Note on the date fixed for
settlement, the applicable Agent shall promptly  notify
the  Company and deliver the Note to the Company,  and,
if such Agent has theretofore paid the Company for such
Note,  the Company will promptly return such  funds  to
such  Agent.  If such failure occurred for  any  reason
other than default by such Agent in the performance  of
its  obligations hereunder, the Company will  reimburse
such  Agent on an equitable basis for its loss  of  the
use  of  the  funds  for  the period  such  funds  were
credited to the Company's account.

SECTION 7.  Additional Covenants of the Company.

           The  Company covenants and agrees  with  the
Agents that:

     A.         Reaffirmation  of  Representations  and
Warranties.  Each acceptance by the Company of an offer
for  the purchase of Notes, and each delivery of  Notes
to  the applicable Agent pursuant to a Terms Agreement,
shall   be  deemed  to  be  an  affirmation  that   the
representations and warranties of the Company contained
in  this  Agreement and in any certificate  theretofore
delivered  to the Agents pursuant hereto are  true  and
correct at the time of such acceptance or sale, as  the
case  may be, and the Company will use its best efforts
to  undertake that such representations and  warranties
will be true and correct at the time of delivery to the
purchaser or his agent, or to the Agents, of  the  Note
or  Notes relating to such acceptance or sale,  as  the
case may be, as though made at and as of each such time
(and  it  is  understood that such representations  and
warranties  shall relate to the Registration Statement,
Prospectus  and  any such certificate  as  amended  and
supplemented to each such time).
     
     B.      Subsequent Delivery of Certificates.  Each
time  that the Registration Statement or the Prospectus
shall  be  amended or supplemented (other  than  by  an
amendment or supplement providing  solely for a  change
in the interest rates of Notes or similar changes, and,
unless  the Agents shall otherwise specify, other  than
by an amendment or supplement which relates exclusively
to  an offering of debt securities other than the Notes
and  other  than by a pricing supplement) or  there  is
filed  with  the  SEC  any  document  incorporated   by
reference  into  the Prospectus unless  waived  by  the
Agents  (other than any Current Report on Form 8-K)  or
(if   required  pursuant  to  the  terms  of  a   Terms
Agreement) the Company sells Notes to an Agent pursuant
to  a  Terms  Agreement, the Company shall  furnish  or
cause  to  be  furnished  to  the  Agents  forthwith  a
certificate dated the date of filing with  the  SEC  of
such  supplement or document, the date of effectiveness
of  such  amendment, or the date of such sale,  as  the
case  may  be, in form reasonably satisfactory  to  the
Agents  to the effect that the statements contained  in
the  certificate  referred to in  Section  5(b)  hereof
which  was  last furnished to the Agents  is  true  and
correct  at  the  time  of such amendment,  supplement,
filing  or sale, as the case may be, as though made  at
and  as of such time (except that such statements shall
be  deemed to relate to the Registration Statement  and
the  Prospectus  as  amended and supplemented  to  such
time) or, in lieu of such certificate, a certificate of
the  same tenor as the certificate referred to in  said
Section  5(b), modified as necessary to relate  to  the
Registration  Statement and the Prospectus  as  amended
and  supplemented  to  the time  of  delivery  of  such
certificate.

     C.    Subsequent Delivery of Legal Opinions.  Each
time  that the Registration Statement or the Prospectus
shall  be  amended or supplemented (other  than  by  an
amendment or supplement providing solely for  a  change
in  the  interest rates of the Notes or similar changes
or  solely  for  the inclusion of additional  financial
information,  and,  unless the Agents  shall  otherwise
specify, other than by an amendment or supplement which
relates  exclusively to an offering of debt  securities
other  than  the  Notes and other  than  by  a  pricing
supplement) or there is filed with the SEC any document
incorporated  by  reference into the Prospectus  unless
waived by the Agents (other than any Current Report  on
Form  8-K  or  Quarterly Report on Form 10-Q),  or  (if
required  pursuant to the terms of a  Terms  Agreement)
the Company sells Notes to an Agent pursuant to a Terms
Agreement,  the Company shall furnish or  cause  to  be
furnished forthwith to the Agents and to counsel to the
Agents  the written opinions of each of Milbank, Tweed,
Hadley  &  McCloy,  counsel to  the  Company,  Doerner,
Saunders,  Daniel & Anderson, Oklahoma counsel  to  the
Company,  and  Wagstaff, Alvis, Stubbeman,  Seamster  &
Longacre,  L.L.P.,  Texas counsel to  the  Company,  or
other counsel satisfactory to the Agents dated the date
of  filing with the SEC of such supplement or document,
the  date  of effectiveness of such amendment,  or  the
date  of  such sale, as the case may be,  in  form  and
substance reasonably satisfactory to the Agents, of the
same  tenor as the respective opinions referred  to  in
Sections  5(a)(1),  5(a)(3)  and  5(a)(4)  hereof,  but
modified,  as  necessary, to relate to the Registration
Statement   and   the   Prospectus   as   amended   and
supplemented  to the time of delivery of such  opinion;
or,  in  lieu of such opinion, counsel last  furnishing
such  opinion  to the Agents shall furnish  the  Agents
with a letter to the effect that the Agents may rely on
such  last opinion to the same extent as though it  was
dated  the  date  of  such letter authorizing  reliance
(except  that statements in such last opinion shall  be
deemed to relate to the Registration Statement and  the
Prospectus as amended and supplemented to the  time  of
delivery of such letter authorizing reliance).

     D.   Subsequent Delivery of Comfort Letters.  Each
time  that the Registration Statement or the Prospectus
shall  be amended or supplemented to include additional
financial  information or there is filed with  the  SEC
any   document  incorporated  by  reference  into   the
Prospectus   which   contains   additional    financial
information unless waived by the Agents (other than  in
a pricing supplement or Current Report on Form 8-K) or,
(if   required  pursuant  to  the  terms  of  a   Terms
Agreement) the Company sells Notes to an Agent pursuant
to  a  Terms Agreement, the Company shall cause  Arthur
Andersen LLP forthwith to furnish the Agents a  letter,
dated  the  date  of effectiveness of  such  amendment,
supplement  or document with the SEC , or the  date  of
such  sale,  as  the  case may be, in  form  reasonably
satisfactory  to the Agents, of the same tenor  as  the
portions of the letter referred to in clauses  (i)  and
(ii)  of Section 5(c) hereof but modified to relate  to
the  Registration Statement and Prospectus, as  amended
and supplemented to the date of such letter, and of the
same  general  tenor  as  the portions  of  the  letter
referred  to in clauses (iii) and (iv) of said  Section
5(c)  with such changes as may be necessary to  reflect
changes   in   the  financial  statements   and   other
information derived from the accounting records of  the
Company;  provided, however, that if  the  Registration
Statement  or the Prospectus is amended or supplemented
solely to include financial information as of and for a
fiscal quarter, Arthur Andersen LLP may limit the scope
of  such  letter to the unaudited financial  statements
included  in  such amendment or supplement  unless  any
other  information included therein of  an  accounting,
financial  or  statistical nature is of such  a  nature
that,  in  the reasonable judgment of the Agents,  such
letter should cover such other information.

SECTION 8.     Indemnification.

      a.    The  Company agrees to indemnify  and  hold
harmless  each of the Agents and each person,  if  any,
who  controls each of the Agents within the meaning  of
Section  15 of the 1933 Act or Section 20 of  the  1934
Act,  from  and  against any and  all  losses,  claims,
damages or liabilities, joint or several, to which such
Agent  or  controlling person may become subject  under
the  1933  Act,  the  1934 Act or  the  common  law  or
otherwise,  and to reimburse each such  Agent  or  such
controlling  person for any reasonable legal  or  other
expenses   (including,   to  the   extent   hereinafter
provided, reasonable counsel fees) incurred  by  it  or
them  in  connection with defending  against  any  such
losses, claims, damages or liabilities, arising out  of
or  based  upon any untrue statement or alleged  untrue
statement   of  a  material  fact  contained   in   the
Registration  Statement or any amendment  thereof,  any
preliminary prospectus or the Prospectus (as amended or
supplemented  if the Company shall have  furnished  any
amendments or supplements thereto), or any omission  or
alleged  omission  to  state therein  a  material  fact
required to be stated therein or necessary to make  the
statements  therein not misleading; provided,  however,
that   the  indemnity  agreement  contained   in   this
subsection  (a)  shall not apply to  any  such  losses,
claims, damages or liabilities arising out of or  based
upon  (i)  any such untrue statement or alleged  untrue
statement, or any such omission or alleged omission, if
such  statement or omission was made in  reliance  upon
and in conformity with information furnished in writing
to  the  Company by any of the Agents for  use  in  the
Registration  Statement  or  the  Prospectus   or   any
amendment  or  supplement to either thereof,  (ii)  any
statement made in the Form T-1 filed by the Trustee  as
an  exhibit to the Registration Statement or (iii)  the
failure  of  any  Agent  to  deliver  a  copy  of   the
Prospectus  (excluding  any documents  incorporated  by
reference),  or  of  the  Prospectus  as   amended   or
supplemented  after  it  shall  have  been  amended  or
supplemented  by the Company (excluding  any  documents
incorporated  by reference), to any person  to  whom  a
copy  of  any  preliminary prospectus shall  have  been
delivered  by or on behalf of such Agent  to  whom  any
Notes  shall  have  been sold by such  Agent,  as  such
delivery may be required by the 1933 Act and the  rules
and regulations of the Commission thereunder.

      b.    Each of the Agents agrees to indemnify  and
hold  harmless  the Company, each of its  officers  who
signs   the   Registration  Statement,  each   of   its
directors, each person who controls the Company  within
the meaning of Section 15 of the 1933 Act or Section 20
of  the 1934 Act, each other Agent and each person,  if
any,  who  so controls any such other Agent,  from  and
against   any  and  all  losses,  claims,  damages   or
liabilities, joint or several, to which any one or more
of them may become subject under the 1933 Act, the 1934
Act  or  the common law or otherwise, and to  reimburse
each of them for any reasonable legal or other expenses
(including,   to   the  extent  hereinafter   provided,
reasonable counsel fees) incurred by them in connection
with defending against any such losses, claims, damages
or liabilities of the character above specified arising
out  of  or  based  upon (i) any  untrue  statement  or
alleged  untrue statement of a material fact  contained
in  the Registration Statement or the Prospectus or any
amendment   to  the  Registration  Statement   or   the
Prospectus or amendment or supplement to the Prospectus
or  upon  any omission or alleged omission to state  in
any  thereof  a  material fact required  to  be  stated
therein or necessary to make the statements therein not
misleading  if such statement or omission was  made  in
reliance   upon  and  in  conformity  with  information
furnished  in writing to the Company by such Agent  for
use in the Registration Statement or the Prospectus  or
any  amendment  or  supplement to  either  thereof,  or
(ii)  the  failure  of such Agent  to  deliver  (either
directly  or  through  the  Managers)  a  copy  of  the
Prospectus  (excluding  any documents  incorporated  by
reference),  or  of  the  Prospectus  as   amended   or
supplemented  after  it  shall  have  been  amended  or
supplemented  by the Company (excluding  any  documents
incorporated  by reference), to any person  to  whom  a
copy  of  any  preliminary prospectus shall  have  been
delivered by or on behalf of such Agent and to whom any
Notes shall have been sold by or through such Agent, as
such  delivery may be required by the 1933 Act and  the
rules and regulations of the Commission thereunder.

     c.   Promptly after receipt by a party indemnified
under this Section 8 (an "indemnified party") of notice
of            the            commencement            of
any action, such indemnified party will, if a claim  in
respect  thereof is to be made against a party granting
an  indemnity  under this Section 8 (the  "indemnifying
party"),  notify the indemnifying party in  writing  of
the commencement thereof; but the omission so to notify
the  indemnifying party will not relieve  it  from  any
liability  which  it may have to any indemnified  party
otherwise than under this Section 8.  In case any  such
action is brought against any indemnified party, and it
notifies  the  indemnifying party of  the  commencement
thereof,  the  indemnifying party will be  entitled  to
participate  therein, and to the  extent  that  it  may
elect  by  written notice delivered to the  indemnified
party  promptly  after receiving the  aforesaid  notice
from  such  indemnified party, to  assume  the  defense
thereof  (thereby conceding that the action in question
is subject to indemnification by the indemnifying party
hereunder),   with   counsel   satisfactory   to   such
indemnified  party;  provided,  however,  that  if  the
defendants  in  any  such  action  include   both   the
indemnified  party and the indemnifying party  and  the
indemnified party shall have reasonably concluded  that
there  may  be  legal defenses available to  it  and/or
other  indemnified parties which are different from  or
additional  to  those  available  to  the  indemnifying
party, the indemnified party or parties shall have  the
right  to select separate counsel to assert and conduct
such legal defenses and to otherwise participate in the
defense  of  such action on behalf of such  indemnified
party  or  parties.  Upon receipt of  notice  from  the
indemnifying  party to such indemnified  party  of  its
election  so to assume the defense of such  action  and
approval  by  the  indemnified party  of  counsel,  the
indemnifying   party  will  not  be  liable   to   such
indemnified party under this  Section  for any legal or
other   expenses   subsequently   incurred   by    such
indemnified  party  in  connection  with  the   defense
thereof  unless  (i) the indemnified party  shall  have
employed  separate  counsel  in  connection  with   the
assertion  of  legal  defenses in accordance  with  the
proviso  to  the  next  preceding  sentence  (it  being
understood, however, that the indemnifying party  shall
not  be  liable  for  the expenses  of  more  than  one
separate counsel, approved by the Agents in the case of
subsection  (a),  representing the indemnified  parties
under  subsection (a) who are parties to such  action),
(ii)  the  indemnifying party shall not  have  employed
counsel  satisfactory  to  the  indemnified  party   to
represent  the  indemnified party within  a  reasonable
time  after  notice of commencement of this  action  or
(iii)   the  indemnifying  party  has  authorized   the
employment of counsel for the indemnified party at  the
expense of the indemnifying party; and except that,  if
clause (i) or (iii) is applicable, such liability shall
be  only in respect of the counsel referred to in  such
clause (i) or (iii).

      d.    If the indemnification provided for in this
Section  8 shall be unenforceable under applicable  law
by  an indemnified party, the indemnifying party agrees
to contribute to such indemnified party with respect to
any and all losses, claims, damages and liabilities for
which such indemnification provided for in this Section
8  shall be unenforceable, in such proportion as  shall
be  appropriate to reflect the relative  fault  of  the
indemnifying party on the one hand and the  indemnified
party      on      the     other     in      connection
with the statements or omissions which have resulted in
such  losses, claims, damages and liabilities, as  well
as   any   other   relevant  equitable  considerations;
provided, however, that no indemnified party guilty  of
fraudulent  misrepresentation (within  the  meaning  of
Section  11(f)  of the 1933 Act) shall be  entitled  to
contribution  from  the  indemnifying  party   if   the
indemnifying  party  is not guilty of  such  fraudulent
misrepresentation.  Relative fault shall be  determined
by reference to, among other things, whether the untrue
or  alleged untrue statement of a material fact or  the
omission  or alleged omission to state a material  fact
relates  to  information supplied by  the  indemnifying
party  or  the indemnified party and each such  party's
relative  intent, knowledge, access to information  and
opportunity to correct or prevent such untrue statement
or  omission.  The Company and each of the Agents agree
that   it   would   not  be  just  and   equitable   if
contributions pursuant to this subparagraph were to  be
determined  solely  by pro rata allocation  or  by  any
other  method of allocation which does not take account
of the equitable considerations referred to above.

      e.    The  indemnity and contribution  agreements
contained in this Section 8 and the representations and
warranties of the Company in the Distribution Agreement
shall remain operative and in full force regardless  of
(i)  any  termination  of  the Distribution  Agreement,
(ii)  any  investigation made by or on  behalf  of  any
Agent  or any person controlling any Agent or by or  on
behalf of the Company, its directors or officers or any
person  controlling the Company and (iii)  delivery  of
and payment for any of the Notes.



SECTION 9.     Payment of Expenses.

      The Company will pay all expenses incident to the
performance  of  its obligations under this  Agreement,
including:

          F.        The qualification of the Notes and the First

     accordance with the provisions of Section 4(i) hereof,
     including filing fees and the reasonable fees  and
     disbursements of counsel for the Agents in connection
     therewith and in connection with the preparation of any
     Blue Sky Survey and any Legal Investment Survey, not
     exceeding, however, $5,000 in the aggregate;

          G.        The printing and delivery to the Agents in
     quantities as hereinabove stated of copies of  the
     Registration Statement and any amendments thereto, and
     of the Prospectus and any amendments or supplements
     thereto,  and  the delivery by the Agents  of  the
     Prospectus and any amendments or supplements thereto in
     connection with solicitations or confirmations of sales
     of the Notes;

          H.        The preparation, printing, reproducing and
     delivery to the Agents of copies of the Indenture and
     all supplements and amendments thereto;

          I.        Any fees charged by rating agencies for the
     rating of the Notes;

          J.        The fees and expenses, if any, incurred with
     respect to any filing with the National Association of
     Securities Dealers, Inc.;

          K.        Any advertising and other out-of-pocket
     expenses  of the Agents incurred with the  written
     approval of the Company;

          L.        The cost of preparing, and providing any
     CUSIP or other identification numbers for, the Notes
     and the First Mortgage Bonds;

          M.        The fees and expenses of any Depositary (as
     defined in the Indenture) and any nominees thereof in
     connection with the Notes; and

          N.        The fees and expenses, if any, incurred in
     connection with any filing with or approval by the OCC
     in connection with the issuance of the Notes and the
     First Mortgage Bonds.

     SECTION  10.     Representations,  Warranties  and
                      Agreements to Survive Delivery.

             All   representations,   warranties    and
agreements   contained   in  this   Agreement   or   in
certificates  of  officers  of  the  Company  submitted
pursuant hereto or thereto, shall remain operative  and
in   full   force   and  effect,  regardless   of   any
investigation made by or on behalf of the Agents or any
controlling person of any Agent, or by or on behalf  of
the  Company,  and shall survive each delivery  of  and
payment for any of the Notes.

SECTION 11.    Termination.

     A.         Termination  of this  Agreement.   This
Agreement  (excluding  any  Terms  Agreement)  may   be
terminated  for any reason, at any time by  either  the
Company  or an Agent upon the giving of three  business
days'  written notice of such termination to the  other
party hereto.

     B.         Termination of a Terms Agreement.   The
applicable  Agent may terminate any Terms Agreement  to
which  it  is a party, immediately upon notice  to  the
Company,  at  any  time prior to  the  Settlement  Date
relating  thereto  (i) 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 Agents, impracticable
to   purchase  the  Notes,  or  (ii)  trading  in   any
securities of the Company has been suspended by the SEC
or  a  national securities exchange, or  if  a  general
banking  moratorium shall have been declared by  either
Federal  or  New York authorities, or (iii) the  rating
assigned by any nationally recognized securities rating
agency to any debt securities of the Company as of  the
Purchase Date shall have been lowered since that  date,
or  (iv)  if  there shall have come to  the  applicable
Agent's attention any facts that would cause such Agent
to  believe  that the Prospectus, at the  time  it  was
required  to  be  delivered to a  purchaser  of  Notes,
contained  an  untrue statement of a material  fact  or
omitted to state a material fact necessary in order  to
make   the   statements  therein,  in  light   of   the
circumstances  existing at the time of  such  delivery,
not  misleading, provided, however, the Agent may  only
terminate such Terms Agreement pursuant to this Section
12(b)(v)  if  the  Agent gives written  notice  to  the
Company  of  such Agent's intention to  terminate  such
Terms  Agreement  pursuant  to  this  Section  12(b)(v)
(setting forth in reasonable detail the Agent's  reason
for  such  termination) and the Company fails,  in  the
reasonable  opinion of the Agent, to correct  any  such
untrue  statement  in or omission from  the  Prospectus
prior to such Settlement Date.

     C.         General.   In  the event  of  any  such
termination,  neither party will have any liability  to
the  other  party hereto, except that  (i)  each  Agent
shall   be   entitled  to  any  commission  earned   in
accordance  with  the third paragraph of  Section  3(a)
hereof,  (ii)  if at the time of termination  (a)  each
Agent shall own any Notes purchased pursuant to a Terms
Agreement with the intention of reselling them  or  (b)
an offer to purchase any of the Notes has been accepted
by  the  Company  but  the  time  of  delivery  to  the
purchaser  or  his agent of the Note or Notes  relating
thereto  has not occurred, the covenants set  forth  in
Sections  4  and 7 hereof shall remain in effect  until
such Notes are so resold or delivered, as the case  may
be,  and  (iii) the covenant set forth in Section  4(h)
hereof,  the  provisions  of  Section  5  hereof,   the
indemnity  and  contribution agreements  set  forth  in
Sections 8 and 9 hereof, and the provisions of Sections
11 and 15 hereof shall remain in effect.

SECTION 12.    Notices.

          Unless otherwise provided herein, all notices
required under the terms and provisions hereof shall be
in  writing, either delivered by hand, by  mail  or  by
telex,  telecopier  or telegram, and  any  such  notice
shall   be  effective  when  received  at  the  address
specified below.

          Re:  Public Service Company of Oklahoma
                         $75,000,000 Medium-Term Notes, Series A

Ladies and Gentlemen:

          We have acted as special counsel for Public

Service Company of Oklahoma, an Oklahoma corporation

(the "Company"), in connection with the transactions

contemplated by the Distribution Agreement dated

February 26, 1996 (the "Distribution Agreement"),

between you and the Company, relating to the proposed

issuance and sale from time to time by the Company of

up to $75,000,000 aggregate principal amount of its

Medium-Term Notes, Series A (the "Notes") under its

Indenture dated as of February 1, 1996, to Liberty Bank

and Trust Company of Tulsa, National Association, as

Trustee (the "Note Trustee"), as supplemented by a

Supplemental Indenture thereto dated as of February 1,

1996 (said Indenture as so supplemented being herein

referred to as the "Indenture").

          We have examined originals, or copies

certified to our satisfaction, of all such corporate

records of the Company, indentures, agreements and

other instruments, certificates of public officials,

certificates of officers and representatives of the

Company and other documents as we have deemed it

necessary to require as a basis for the opinions

hereinafter expressed.  In our examination we have

assumed the genuineness of all signatures and the

authenticity of all documents submitted to us as

originals and the conformity with the originals of all

documents submitted to us as copies and the

authenticity of the originals of such latter documents.

As to various questions of fact material to such

opinions we have, when relevant facts were not

independently established, relied upon certifications

by officers of the Company and other appropriate

persons and statements contained in the Registration

Statement hereinafter mentioned.

          Based upon the foregoing, and having regard

to legal considerations which we deem relevant, we are

of the opinion that:

          1.  The Company is a corporation validly
     existing under the laws of the State of Oklahoma.

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

          3.  Each of the Indenture and the Indenture
     dated as of July 1, 1945, as supplemented by
     several supplemental indentures, including a
     Supplemental Indenture dated as of February 1,
     1996 (said Indenture as so supplemented being
     hereinafter called the "First Mortgage
     Indenture"), under which Liberty Bank and Trust
     Company of Tulsa, National Association, is Trustee
     (the "First Mortgage Trustee"), has been duly and
     validly authorized by the necessary corporate
     action by the Company, has been duly and validly
     executed and delivered by the Company and is a
     valid and binding obligation of the Company
     enforceable against the Company in accordance with
     its terms, subject, however, to the fact that
     certain of the remedial provisions thereof may be
     limited or rendered unenforceable by applicable
     laws, including the laws of the States wherein the
     mortgaged property is situated (but said laws do
     not, in our opinion, make the remedies afforded by
     the Indenture and the First Mortgage Indenture
     inadequate for the realization of the benefits of
     the security provided thereby) and except (a) as
     enforceability may be limited by bankruptcy,
     insolvency, reorganization, moratorium or other
     similar laws of general applicability affecting
     the enforcement of creditors' rights, and (b) that
     such enforceability may be limited by the
     application of general principles of equity
     (regardless of whether considered in a proceeding
     in equity or at law), including without limitation
     (i) the possible unavailability of specific
     performance, injunctive relief or any other
     equitable remedies and (ii) concepts of
     materiality, reasonableness, good faith and fair
     dealing.

          4.  The issue and sale of the Notes and the
     issuance and delivery by the Company of the First
     Mortgage Bonds (the "First Mortgage Bonds") under
     the First Mortgage Indenture to the Note Trustee
     as collateral for the Notes in accordance with the
     terms of the Indenture have been duly and validly
     authorized by the Company by the resolutions
     adopted by the Board of Directors on January 16,
     1996 (the "Board Resolutions").  The Notes, when
     duly executed, authenticated, completed and
     delivered to and paid for by the purchasers
     thereof as contemplated by and in accordance with
     the Indenture, the Board Resolutions and the Order
     (as defined in paragraph 6 below) and the First
     Mortgage Bonds, when duly executed, authenticated,
     completed and delivered to the Note Trustee as
     contemplated by and in accordance with the First
     Mortgage Indenture, the Board Resolutions and the
     Order will be (subject to the qualifications
     stated in paragraph 3 above) valid and binding
     obligations of the Company, entitled to the
     benefit of the Indenture in the case of the Notes,
     and secured, in the case of the First Mortgage
     Bonds, by the lien of and entitled to the benefits
     of the First Mortgage Indenture.

          5.  The Notes and the Indenture and the First
     Mortgage Bonds and First Mortgage Indenture,
     conform as to legal matters, in all material
     respects, with the statements concerning them made
     in the Prospectus dated February 23, 1996 (the
     "Base Prospectus") under the caption "Description
     of the Senior Notes" and "Description of the
     Senior Note Mortgage Bonds" and in the Prospectus
     Supplement dated February 26, 1996 (the
     "Prospectus Supplement", and together with the
     Base Prospectus, the "Prospectus") under the
     caption "Description of the Notes" and such
     statements accurately set forth, in all material
     respects, the matters respecting the Notes and the
     Indenture and the First Mortgage Bonds and First
     Mortgage Indenture, which are required to be set
     forth in the Prospectus, as supplemented by the
     Prospectus Supplement, by the Securities Act of
     1933, as amended (the "Securities Act"), and the
     Trust Indenture Act of 1939, as amended (the
     "TIA"), and the rules and regulations under said
     Acts (other than the accounting provisions
     thereof, with respect to the requirements of which
     we express no opinion or belief); and each of the
     Indenture and the First Mortgage Indenture has
     been qualified under the TIA.

          6.  The order (the "Order") of the Oklahoma
     Corporation Commission (the "Oklahoma Commission")
     referred to in subsection (a)(xi)(i) of Section 2
     of the Distribution Agreement has been duly
     entered and, to the best of our knowledge, is in
     full force and effect.

          7.  The Company is exempt in accordance with
     Rule 52 under the Public Utility Holding Company
     Act of 1935, as amended, from the requirement for
     an order of the Securities and Exchange Commission
     (the "Commission") under said Act with respect to
     the issue and sale of the Notes and the issue and
     delivery of the First Mortgage Bonds.

          8.  Except for the order of the Commission
     entered with respect to the Registration Statement
     as contemplated in paragraph 9 below, no approval,
     authorization, consent, certificate or order of
     any Federal commission or regulatory authority is
     necessary with respect to the execution and
     delivery of the Indenture and the First Mortgage
     Indenture, the issue and sale of the Notes, or the
     issue and delivery of the First Mortgage Bonds by
     the Company as contemplated in the Distribution
     Agreement.

          9.  The Registration Statement on Form S-3
     with respect to the Notes (Registration No. 333-
     00973) (the "Registration Statement") has become
     effective under the Securities Act, and, to the
     best of our knowledge, no stop order suspending
     the effectiveness of the Registration Statement
     has been issued and no proceedings for such
     purpose have been instituted or are pending or
     threatened under the Securities Act.

          10.  The Registration Statement, the
     Prospectus and the Prospectus Supplement, in each
     case including the Incorporated Documents (as
     defined below) (other than financial statements,
     financial data, statistical data and supporting
     schedules included or incorporated by reference
     therein, as to which we express no opinion or
     belief) as of their respective effective, issue or
     filing dates appear on their face to be
     appropriately responsive in all material respects
     to the requirements of the Securities Act (or,
     where appropriate, the Securities Exchange Act of
     1934, as amended) and the rules and regulations of
     the Commission thereunder.

          We have made no examination and express no

opinion as to the Company's title to any of its

property, as to the existence of any liens, charges or

encumbrances thereon (other than the lien of the First

Mortgage Indenture), or as to the filing or recording

of the Indenture or First Mortgage Indenture, and to

the extent that the opinions hereinabove expressed

involve such matters, we have examined and relied upon

the below-mentioned opinions of counsel for the

Company.

          The Registration Statement was filed on Form

S-3 under the Securities Act and, accordingly, the

Prospectus does not necessarily contain a current

description of the Company's business and affairs since

Form S-3 provides for the incorporation by reference of

certain documents filed with the Commission which

contain descriptions as of various dates.  We

participated in the preparation of the Registration

Statement and the Prospectus and we have reviewed

certain documents filed by the Company under the

Exchange Act, which are incorporated by reference in

the Prospectus (such documents listed in the Prospectus

as being incorporated by reference are herein called

the "Incorporated Documents").  Although we have not

independently verified the accuracy, completeness or

fairness of the statements contained therein or in the

Incorporated Documents, none of the foregoing disclosed

to us any information which gave us reason to believe

that the Registration Statement, the Prospectus or the

Incorporated Documents, considered as a whole on the

respective effective date of the Registration Statement

and on the date hereof, contained or contain any untrue

statement of a material fact or omitted or omit to

state a material fact required to be stated therein or

necessary in order to make the statements therein not

misleading.  We express no opinion as to any document

filed by the Company under the Exchange Act, whether

prior or subsequent to such effective date, except to

the extent that such documents are Incorporated

Documents read together with the Registration Statement

or the Prospectus and considered as a whole, nor do we

express any opinion as to the operating statistics,

financial statements or other financial data included

in or omitted from, or incorporated by reference in,

the Registration Statement, the Prospectus or the

Incorporated Documents.

          In rendering the opinion set forth in

paragraph 4 above, we have necessarily assumed that, at

the time of any issuance, sale and delivery of each

Note, (a) the authorization of the Notes will not have

been modified or rescinded and there will not have

occurred any change in the law affecting the validity

or enforceability of such Note and that each Note will

conform to the draft form of the Notes examined by us

and that the issuance and delivery of such Note, and

the compliance by the Company with the terms of such

Note, will not violate any applicable law, or result in

a violation of the Company's certificate of

incorporation or by-laws, any instrument or agreement

then binding upon the Company, or any restriction

imposed by any court or governmental body having

jurisdiction over the Company and (b) the order of the

Oklahoma Commission referred to in paragraph 6 above is

in full force and effect and has not been modified or

amended by the Oklahoma Commission, and the Company is

in compliance therewith.

          In rendering the opinions hereinabove

expressed, we have relied, to the extent pertinent,

with your permission upon the opinions of even date

hereof, delivered to you concurrently herewith, of

Messrs. Doerner, Saunders, Daniel & Anderson, Tulsa,

Oklahoma, and Messrs. Wagstaff, Alvis, Stubbeman,

Seamster & Longacre, L.L.P., Abilene, Texas, special

counsel in the State of Texas for the Company, as to

matters governed by Oklahoma and Texas law,

respectively, and as to such matters, the opinions

hereinabove expressed are subject to all

qualifications, limitations, assumptions and reliances,

and other considerations, therein set forth.

          We do not express any opinion as to matters

governed by any laws other than the laws of the State

of New York, the Federal laws of the United States of

America and, to the extent hereinabove stated, in

reliance on said opinions of said counsel for the

Company, the laws of the States of Oklahoma and Texas.

                                   Very truly yours,

RBW/DBB

                    Re:  $75,000,000 Aggregate
               Principal Amount
               of Medium-Term Notes, Series A

Ladies and Gentlemen:

          This opinion is addressed to you as the
agents (the "Agents") named in the Distribution
Agreement dated February 26, 1996 (the "Distribution
Agreement") between Public Service Company of Oklahoma,
an Oklahoma corporation (the "Company"), and each of
the Agents relating to the offer and sale from time to
time of up to $75,000,000 aggregate principal amount of
the Company's Medium-Term Notes, Series A (the
"Notes").  The Notes will be issued pursuant to the
indenture dated as of February 1, 1996, as supplemented
by the First Supplemental Indenture dated as of
February 1, 1996 thereto (collectively, the
"Indenture"), between the Company and Liberty Bank and
Trust Company of Tulsa, National Association, as
trustee (the "Trustee").  Until the Release Date (as
defined in the Indenture), the Notes will be secured as
to payment of principal and interest by one or more
series of First Mortgage Bonds (the "First Mortgage
Bonds") pledged and delivered by the Company to the
Trustee.  The First Mortgage Bonds will be issued
pursuant to the provisions of the Company's Indenture
dated July 1, 1945, as amended and supplemented to the
date hereof (collectively, the "First Mortgage
Indenture") as the same may from time to time hereafter
be amended or supplemented, to Liberty Bank and Trust
Company of Tulsa, National Association, as trustee.
Capitalized terms not defined herein have the meanings
set forth in the Distribution Agreement.

          As special counsel for the Agents, we have,
among other things, participated with officers and
representatives of the Company, including its counsel
and independent public accountants, and representatives
of the Agents in the preparation of the Company's
Registration Statement on Form S-3 (Registration No.
333-00973), filed on February 15, 1996 with the
Securities and Exchange Commission (the "Commission")
under the Securities Act of 1933, as amended (the
"Act"), which registration statement was declared
effective by the Commission on February 23, 1996.  Such
registration statement (including all materials
incorporated by reference therein pursuant to Item 12
of Form S-3 under the Act at the date hereof (the
"Incorporated Documents")) is hereinafter referred to
as the "Registration Statement."  The Company's
Prospectus dated February 23, 1996 (including the
Incorporated Documents) included in the Registration
Statement (the "Prospectus"), as supplemented by the
Prospectus Supplement dated February 26, 1996 (the
"Prospectus Supplement") relating to the Notes, is
hereinafter referred to collectively as the "Final
Prospectus."

          Pursuant to the requirement of Section
5(a)(2) of the Distribution Agreement, this will advise
you that in the opinion of the undersigned:

          (1)  Each of the Indenture and the First
Mortgage Indenture has been duly and validly authorized
by the necessary corporate action by the Company, has
been duly and validly executed and delivered by the
Company and is the valid and binding obligation of the
Company enforceable against the Company in accordance
with its terms, subject, as to enforcement, (x) to the
fact that certain of the remedial provisions thereof
may be limited or rendered unenforceable by laws of the
States wherein the mortgaged property is situated (but
said laws do not, in our opinion, make the remedies
afforded by the Indenture and the First Mortgage
Indenture inadequate for the realization of the
benefits of the security provided thereby) and (y) to
bankruptcy, insolvency, reorganization, moratorium or
other similar laws relating to or affecting the
enforcement of creditors' rights generally; to the
effects of the provisions of the Bankruptcy Reform Act
of 1978, as amended, on the validity of the lien of the
First Mortgage Indenture with respect to the property
acquired or proceeds realized by the Company after the
commencement of bankruptcy proceedings with respect to
the Company; and to the effects of general principles
of equity (regardless of whether enforceability is
considered in a proceeding in equity or at law);

          (2)  The issue and sale of the Notes and the
issue and delivery of the First Mortgage Bonds by the
Company in accordance with the terms of the
Distribution Agreement have been duly and validly
authorized by the Company.  The Notes, when duly
executed, authenticated and delivered against payment
of the agreed consideration therefor and the First
Mortgage Bonds, when duly executed, authenticated and
delivered, in each case in accordance with the terms of
the Distribution Agreement, will be valid and binding
obligations of the Company, secured, in the case of the
First Mortgage Bonds, by the lien of and entitled to
the benefits of the First Mortgage Indenture, subject,
as to enforcement, (i) to the fact that certain of the
remedial provisions thereof may be limited or rendered
unenforceable by the laws of the States wherein the
mortgaged property is situated (but said laws do not,
in our opinion, make the remedies afforded by the
Indenture and the First Mortgage Indenture inadequate
for the realization of the benefits of the security
provided thereby) and (ii) to bankruptcy, insolvency,
reorganization, moratorium or other similar laws
relating to or affecting the enforcement of creditors'
rights generally; to the effects of the provisions of
the Bankruptcy Reform Act of 1978, as amended, on the
validity of the lien of the First Mortgage Indenture
with respect to the property acquired or proceeds
realized by the Company after the commencement of
bankruptcy proceedings with respect to the Company; and
to the effects of general principles of equity
(regardless of whether enforceability is considered in
a proceeding in equity or at law);

          (3)  The Notes and the Indenture and the
First Mortgage Bonds and the First Mortgage Indenture
conform as to legal matters, in all material respects,
with the statements concerning them made in the
Prospectus under the captions "Description of Senior
Notes" and "Description of Senior Note Mortgage Bonds"
and in the Prospectus Supplement under the caption
"Description of the Notes" and such statements
accurately set forth, in all material respects, the
matters respecting the Notes and the Indenture and the
First Mortgage Bonds and the First Mortgage Indenture
which are required to be set forth in the Final
Prospectus by the Act and the Trust Indenture Act of
1939, as amended (the "1939 Act"), and the rules and
regulations under said Acts (other than the accounting
provisions thereof, with respect to the requirements of
which we need express no opinion or belief); and each
of the Indenture and the First Mortgage Indenture has
been qualified under the 1939 Act;

          (4)  The Registration Statement has become
effective under the Act, and, to our knowledge, no stop
order suspending the effectiveness of the Registration
Statement has been issued and no proceedings for such
purpose have been instituted or are pending or
threatened under the Act;

          (5)  The Registration Statement, the
Prospectus and the Prospectus Supplement (other than
the financial statements, financial data, statistical
data and supporting schedules included or incorporated
by reference therein, as to which we express no opinion
or belief), in each case excluding the Incorporated
Documents, as of their respective effective or issue
dates, complied as to form, in all material respects,
with the requirements of the Act and the rules and
regulations thereunder; and

          (6)  The Distribution Agreement has been duly
authorized, executed and delivered by the Company.

          We have made no examination and express no
opinion as to the Company's title to any of its
property, as to the existence of any liens, charges or
encumbrances thereon (other than the lien of the First
Mortgage Indenture), or as to the filing or recording
of the Indenture or the First Mortgage Indenture, and
to the extent that the opinions hereinabove expressed
may involve such matters, we have examined and relied
upon the below-mentioned opinions of counsel for the
Company.

          In the course of the preparation of the
Registration Statement and the Final Prospectus, we
have considered the information set forth therein in
light of the matters required to be set forth therein
and, as noted above, we have participated in
conferences with your representatives and officers and
representatives of the Company, including its counsel
and independent public accountants, during the course
of which the contents of the Registration Statement and
the Final Prospectus and related matters were
discussed.  Except as otherwise expressly stated
herein, we have not independently checked the accuracy
or completeness of, or otherwise verified, and
accordingly are not passing upon, and do not assume
responsibility for, the accuracy, completeness or
fairness of the statements contained in the
Registration Statement or the Final Prospectus; and we
have relied as to materiality, to a large extent, upon
the judgment of officers and representatives of the
Company.  However, as a result of such consideration
and participation, nothing has come to our attention
that causes us to believe that the Registration
Statement (other than the financial statements,
financial data, statistical data and supporting
schedules included or incorporated by reference
therein, as to which we express no opinion or belief),
at the time it became effective, contained an untrue
statement of a material fact or omitted to state a
material fact required to be stated therein or
necessary to make the statements therein not misleading
or that the Final Prospectus (other than the financial
statements, financial data, statistical data and
supporting schedules included or incorporated by
reference therein, as to which we express no opinion or
belief), as of the date hereof, includes an untrue
statement of a material fact or omits to state a
material fact necessary in order to make the statements
therein, in the light of the circumstances under which
they were made, not misleading.

          In rendering the opinion set forth in
paragraph 2 above, we have necessarily assumed that, at
the time of any issuance, sale and delivery of each
Note, (a) the authorization of the Notes will not have
been modified or rescinded and there will not have
occurred any change in the law affecting the validity
or enforceability of such Note and that each Note will
conform to the draft form of the Notes examined by us
and that the issuance and delivery of such Note, and
the compliance by the Company with the terms of such
Note, will not violate any applicable law, or result in
a violation of the Company's certificate of
incorporation or by-laws, any instrument or agreement
then binding upon the Company, or any restriction
imposed by any court or governmental body having
jurisdiction over the Company and (b) the order of the
OCC referred to in Section 2(a)(x) of the Distribution
Agreement is in full force and effect and has not been
modified or amended by the OCC, and the Company is in
compliance therewith.

          For the purpose of rendering the foregoing
opinions, we have relied, as to various questions of
fact material to such opinions, upon the
representations made in the Distribution Agreement,
certificates of officers of the Company and
certificates of the Trustee.  We also have examined
originals, or copies of originals certified to our
satisfaction, of such agreements, documents,
certificates and other statements of government
officials and other instruments, have examined such
questions of law and have satisfied ourselves as to
such matters of fact as we have considered relevant and
necessary as a basis for this opinion.  We have assumed
the authenticity of all documents submitted to us as
originals, the genuineness of all signatures, the legal
capacity of all natural persons and the conformity with
the original documents of any copies thereof submitted
to us for our examination.

          In rendering the foregoing opinions, we have
relied, with your permission, exclusively upon the
opinions of even date herewith, delivered to you
concurrently herewith, of Messrs. Doerner, Saunders,
Daniel & Anderson, Tulsa, Oklahoma, counsel in the
State of Oklahoma for the Company, and Messrs.
Wagstaff, Alvis, Stubbeman, Seamster & Longacre,
L.L.P., Abilene, Texas, counsel in the State of Texas
for the Company, as to all matters governed by Oklahoma
and Texas law, respectively, and as to such matters,
our foregoing opinions are subject to all
qualifications, limitations, assumptions, reliances and
other considerations therein set forth.

          This opinion is limited to the federal laws
of the United States of America and the laws of the
State of New York, and to the extent hereinabove
stated, in reliance on such opinions of such counsel
for the Company, the laws of the States of Oklahoma and
Texas.

          This opinion is being delivered solely for
the benefit of the persons to whom it is addressed;
accordingly, it may not be quoted, filed with any
governmental authority or other regulatory agency or
otherwise circulated or utilized for any other purpose
without prior written consent.
                                      Very truly yours,

New York, New York 10036

Ladies and Gentlemen:

      This  opinion is addressed to you as Agents under
the  Distribution  Agreement, dated February  26,  1996
(the  "Distribution Agreement"), between Public Service
Company  of  Oklahoma,  an  Oklahoma  corporation  (the
"Company"), and you, pursuant to which the Company will
issue  and sell through you as Agents up to $75,000,000
in  Medium-Term  Notes, Series A (the  "Notes").   This
opinion  is given pursuant to the provisions of Section
5(a)(3) of the Distribution Agreement.  All terms  used
herein  which  are not otherwise defined  herein  shall
have  the  meanings given or assigned to such terms  in
the Distribution Agreement.

      The  Notes are being issued under and secured  by
the  Indenture dated February 1, 1996 and  between  the
Company  and Liberty Bank and Trust Company  of  Tulsa,
National  Association,  as Trustee  (the  "Indenture").
Until  the  Release Date (as defined in the Indenture),
the  Notes  will be secured as to payment of  principal
and  interest  by  one or more series  of  Senior  Note
Mortgage  Bonds  (the  "Senior  Note  Mortgage  Bonds")
issued,  pledged and delivered by the  Company  to  the
Trustee.  The Senior Note Mortgage Bonds will be issued
pursuant  to the provisions of the Company's  Indenture
dated   July  1,  1945,  as  supplemented  by   several
supplemental   indentures,   including   a   Supplement
Indenture  dated  as of February 1,  1996  (the  "First
Mortgage Supplemental Indenture") (said Indenture as so
supplemented  being  hereinafter  called   the   "First
Mortgage  Indenture"), between the Company and  you  in
your  capacity  as  Trustee under  the  First  Mortgage
Indenture (the "First Mortgage Trustee").

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

      Based  upon  our  examination of such  documents,
records  and  matters  of law  as  we  have  considered
relevant  in the premises, and upon our familiarity  as
counsel  for the Company in the State of Oklahoma  with
its  property  and general affairs in said  State,  and
subject to the assumptions and qualifications set forth
below, it is our opinion that:

      1.  The Company has been duly incorporated and is
a  validly existing corporation under the laws  of  the
State  of  Oklahoma  and  is  duly  authorized  by  its
Restated  Certificate of Incorporation to  conduct  the
businesses in which it is engaged as described  in  the
Prospectus and the Prospectus Supplement.  The  Company
has the legal right to function and operate as a public
utility  in  the  State of Oklahoma  supplying  therein
electric service.

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

      3.   Each of the Indenture and the First Mortgage
Indenture has been duly and validly authorized  by  all
necessary  corporate action of the  Company,  has  been
duly and validly executed and delivered by the Company,
and  is  a valid and binding obligation of the Company,
enforceable against the Company in accordance with  its
terms,  subject, however, to the fact that  certain  of
the remedial provisions of the First Mortgage Indenture
may be limited or rendered unenforceable by the laws of
the  States wherein the mortgaged property is  situated
(but  said  laws  do  not, in  our  opinion,  make  the
remedies  afforded  by  the  First  Mortgage  Indenture
inadequate for the realization of the benefits  of  the
security  provided thereby), and except (a) as  may  be
limited   by  bankruptcy,  insolvency,  reorganization,
moratorium   or   other   similar   laws   of   general
applicability  affecting the enforcement of  creditors'
rights, and (b) that such enforceability may be limited
by  the  application  of general principles  of  equity
(regardless  of whether considered in a  proceeding  in
equity or at law), including without limitation (i) the
possible   unavailability  of   specific   performance,
injunctive relief or any other equitable remedies,  and
(ii)  concepts  of  materiality,  reasonableness,  good
faith and fair dealing.

     4.  The issue and sale of the Notes and the Senior
Note  Mortgage Bonds by the Company in accordance  with
the  terms of the Distribution Agreement have been duly
and  validly  authorized  by  all  necessary  corporate
action.   The  Notes, when duly executed, authenticated
and  delivered  against payment  of  the  consideration
therefor, and the Senior Note Mortgage Bonds when  duly
executed,  and  authenticated  and  delivered  to   the
Trustee  will be (subject to the qualifications  stated
in  paragraph 3 above) valid and binding obligations of
the  Company  and,  in  the case  of  the  Senior  Note
Mortgage Bonds, secured by the lien of and entitled  to
the benefits of the First Mortgage Indenture.

      5.  The Company has good and sufficient title  to
all  or  substantially all the permanent fixed electric
utility  properties now owned by it,  situated  in  the
State   of  Oklahoma,  including  those  described   or
referred  to  in  the  Prospectus  and  the  Prospectus
Supplement,  except  as  otherwise  indicated  therein,
subject   only  to  the  lien  of  the  First  Mortgage
Indenture  and to permitted encumbrances and liens  and
prepaid liens (as those terms are defined in the  First
Mortgage  Indenture)  and to the  junior  lien  on  the
Company's  Northeastern Station securing project  bonds
issued to finance the construction of Units 3 and 4  of
said  Station.   The First Mortgage Indenture,  subject
only  to  permitted encumbrances and liens and  prepaid
liens, constitutes a valid, direct first mortgage  lien
upon all such fixed properties of the Company (with the
exception  of  the  properties  expressly  excepted  or
excluded from such lien).  All permanent fixed property
hereafter acquired by the Company and situated  in  the
State of Oklahoma (other than property of the character
of that expressly excepted or excluded from the lien of
the   First   Mortgage  Indenture)  will,   upon   such
acquisition,  become subject to the lien of  the  First
Mortgage Indenture, subject, however, to such permitted
encumbrances  and  liens and prepaid liens,  any  liens
existing or placed on such property at the time of  the
acquisition  thereof  by  the Company,  and  any  liens
thereon  which might intervene prior to the filing  for
record  of  the  instrument  by  which  title  to  such
property  is  acquired by the Company,  and  except  as
provisions  of  the  Bankruptcy  Code  may  affect  the
validity  of  the lien of the First Mortgage  Indenture
with   respect  to  property  acquired,  and  proceeds,
products,  rents,  issue  or profits  of  the  property
subject to such lien realized, after commencement of  a
case under such Code.

      6.   The First Mortgage Indenture (other than the
First  Mortgage Supplemental Indenture) has  been  duly
filed for record as a mortgage or deed of trust of real
and personal property in the office of the Secretary of
State  of the State of Oklahoma and the filing  of  the
First Mortgage Supplemental Indenture in the office  of
the  Secretary  of State of the State of Oklahoma  will
constitute all of the action required under the laws of
the State of Oklahoma to give notice of the lien of the
First Mortgage Indenture.

       7.    The   Company  has  valid  and  subsisting
franchises,  licenses  and  permits  relating  to   its
operations  in  the State of Oklahoma, authorizing  the
Company  to  carry  on its present operations  in  said
State.

      8.  The execution and delivery by the Company  of
any  supplemental indenture relating to the  Notes  and
issuance and sale of the Notes by the Company, and  the
execution   and   delivery  by  the  Company   of   any
supplemental  indenture relating  to  the  Senior  Note
Mortgage Bonds and issuance of the Senior Note Mortgage
Bonds  by the Company, each upon terms consistent  with
the Distribution Agreement, have been authorized by  an
Amended  Order  and  Certificate of  Authority  of  the
Corporation Commission of the State of Oklahoma,  dated
February  22,  1996, which Order has been duly  entered
and, to the best of our knowledge, is in full force and
effect.   No further approval, authorization,  consent,
certificate  or  order  of  any  state  commission   or
regulatory  authority  in  Oklahoma  (other   than   in
connection or in compliance with the securities or Blue
Sky  laws or regulations of the jurisdictions in  which
any  of  the Notes and Senior Note Mortgage  Bonds  may
have  been  or are to be offered for sale or  sold)  is
necessary with respect to the execution and delivery of
the  Indenture and the First Mortgage Indenture or  the
issuance and sale of the Notes and Senior Note Mortgage
Bonds   by   the   Company  as  contemplated   by   the
Distribution Agreement.

      9.   Except as set forth in the Prospectus or the
Prospectus  Supplement and except as set forth  in  the
following sentence, to the best of our knowledge  there
is  no  material  litigation or other legal  proceeding
pending  to  which the Company is a party or  of  which
property  of  the Company is the subject, and,  to  the
best   of   our   knowledge,  no  such  litigation   or
proceedings   are  contemplated.   There  are   various
routine   litigation,  claims  and  other   proceedings
pending  against the Company or involving  property  of
the  Company,  which  are common  or  incident  to  the
business in which the Company is engaged but which,  in
the  aggregate,  are not significant (in  our  opinion)
from  the  standpoint of the total assets  and  overall
operations of the Company.

       10.   The  statements,  if  any,  made  in   the
Prospectus  or  the  Prospectus  Supplement  which  are
stated therein to have been made on our authority, have
been reviewed by us and, as to matters of law and legal
conclusions, are correct.

     This opinion is limited exclusively to the laws of
the  State  of Oklahoma which are presently in  effect.
We  note  that the Indenture and the Notes  are  to  be
governed  by and construed in accordance with the  laws
of  the  State of New York.  In rendering our  opinions
herein  with  respect  to  the  enforceability  of  the
Indenture and the Notes, we have assumed that the  laws
of  the  State of New York are the same as the laws  of
Oklahoma.

     The phrase "to the best of our knowledge," as used
herein,  refers to matters within our actual knowledge.
Except  as  otherwise stated herein, we  have  made  no
independent  investigation  of  documents  and  records
pertaining  to  the Company not in our possession,  nor
have  we  made an independent search of the records  of
any judicial authority or governmental agency.

     We undertake no obligation to update or supplement
our  opinions herein as a result of events  or  actions
occurring after the date hereof.

      In  rendering our opinions herein, we  have  with
your  permission relied upon the opinion of  even  date
hereof,  delivered  to  you concurrently  herewith,  of
Messrs.   Wagstaff,   Alvis,  Stubbeman,   Seamster   &
Longacre, L.L.P. of Abilene, Texas.

      We  hereby consent to the reliance as to  matters
governed  by  Oklahoma law by Messrs.  Milbank,  Tweed,
Hadley  & McCloy and Messrs. Sidley & Austin, in giving
their respective opinions of even date herewith on  our
opinions  set  forth herein.  The opinions  herein  are
rendered  solely  for  the benefit  of  the  Agents  in
connection  with  the  requirement  set  forth  in  the
Distribution  Agreement.   Without  our  prior  written
consent this opinion may not be quoted in whole  or  in
part or furnished to or relied upon by any other person
or entity.

                                   Very truly yours,

                          DOERNER, SAUNDERS, DANIEL & ANDERSON




                                              EXHIBIT E

Ladies and Gentlemen:

     This opinion is addressed to you as the Agents
(the "Agents") under Section 5(a)(4) of the
Distribution Agreement (the "Distribution Agreement"),
dated February 26, 1996, between Public Service Company
of Oklahoma (the "Company") and you, pursuant to which
the Company will issue and sell and the Agents will
purchase from time to time up to $75,000,000 aggregate
principal amount of Medium Term Notes (the "Notes").
The Notes will be secured by First Mortgage Bonds (the
"First Mortgage Bonds") issued by the Company.

     The First Mortgage Bonds are being issued under
and secured by that one certain indenture dated July 1,
1945, as amended and supplemented, by and between the
Company and Liberty Bank and Trust Company of Tulsa,
National Association, as Trustee (the "First Mortgage
Indenture").  Terms used with initial capital letters
herein and not otherwise defined herein shall have the
meanings assigned thereto in the Distribution
Agreement.

     Based upon our examination of such documents,
records, and matters of law as we have considered
relevant in the premises, as special counsel for the
Company in the State of Texas, it is our opinion that:

     (i)  The Company is duly qualified to transact
business as a foreign corporation in the State of
Texas.

     (ii)  The Company has good and sufficient title to
all or substantially all the permanent fixed electric
utility properties now owned by it situated in the
State of Texas, including those described or referred
to in the Prospectus, except as otherwise indicated
therein, subject only to the lien of the First Mortgage
Indenture and to permitted encumbrances and liens and
prepaid liens, as defined in the First Mortgage
Indenture.  The First Mortgage Indenture constitutes a
valid, direct first mortgage lien, subject only to
permitted encumbrances and liens and prepaid liens,
upon all such fixed properties of the Company (with the
exception of the properties expressly excepted or
excluded from such lien of the First Mortgage
Indenture).  All permanent fixed property hereafter
acquired by the Company and situated in the State of
Texas (other than property of the character of that
expressly excepted or excluded from the lien of the
First Mortgage Indenture) will, upon such acquisition,
become subject to the lien of the First Mortgage
Indenture, subject, however, to such permitted
encumbrances and liens and prepaid liens, any liens
existing or placed on such property at the time of the
acquisition thereof by the Company, and any liens
thereon which might intervene prior to the filing for
record of the instrument by which title to such
property is acquired by the Company and except as
provisions of the Bankruptcy Code may affect the
validity of the lien of the First Mortgage Indenture
with respect to property acquired, and proceeds,
products, rents, issue or profits of the property
subject to such lien realized, after commencement of a
case under such Code.

     (iii)  The laws of the State of Texas affecting
the remedies for the enforcement of the security
provided for in the First Mortgage Indenture do not, in
our opinion, make such remedies inadequate for the
realization of the benefits of such security.

     (iv)  With the exception of that one certain
supplemental indenture dated as of February 1, 1996,
providing for "First Mortgage Bonds, Series X," which
we understand will be forthwith duly recorded as a
utility security instrument in the office of the
Secretary of State of the State of Texas, the First
Mortgage Indenture has been duly so recorded as a
utility security instrument and notices of utility
security instruments affecting real property have
heretofore been duly filed in each of the counties in
the State of Texas in which property owned by the
Company and subject to the lien of the First Mortgage
Indenture is situated, in such manner as to make
effective the lien intended to be created by the First
Mortgage Indenture.  Such recordation and filings
constitute all of the action required under the laws of
the State of Texas to give notice of the lien of the
First Mortgage Indenture.  No recording or other taxes
of the State of Texas are required by law in connection
with the issuance of the Notes and First Mortgage Bonds
or for the effectiveness of the lien of the First
Mortgage Indenture as security for the First Mortgage
Bonds.

     (v)  As presently conducted, the Company's
operations in the State of Texas require no franchises,
licenses or permits, other than Certificates of
Convenience and Necessity pertaining to its Texas
properties which have been issued by the Public Utility
Commission of Texas.

     (vi)  No approval, authorization, consent,
certificate or order of any commission or regulatory
authority of the State of Texas (other than in
connection or in compliance with the securities or
"blue sky" laws or regulations of the State of Texas)
is necessary with respect to the execution and delivery
of the First Mortgage Indenture or the issuance and
sale of the Notes and the First Mortgage Bonds by the
Company as contemplated by the Distribution Agreement.

     All statements in this opinion assume and are
subject to the prompt and timely recording of the
supplemental indenture providing for First Mortgage
Bonds, Series X, as set out in section (iv) hereof.  We
do not herein express any opinion as to any matters
governed by any laws other than the laws of the State
of Texas.  We hereby consent to the reliance as to
matters governed by Texas law by Messrs. Milbank,
Tweed, Hadley & McCloy, Messrs. Doerner, Saunders,
Daniel & Anderson and Messrs. Sidley & Austin, in
giving their opinions of even date herewith, on our
opinions set forth herein.

                                Very truly yours,

          Medium Term Notes, Series A (the "Notes") in
the aggregate principal amount of up to $75,000,000 are
to be offered on a continuing basis by Public Service
Company of Oklahoma, an Oklahoma corporation  (the
"Company"), through Smith Barney Inc. and Morgan
Stanley & Co. Incorporated who, as agents (each an
"Agent," and, collectively, the "Agents"), have agreed
to use their reasonable best efforts to solicit offers
to purchase the Notes from the Company.  The Agents may
also purchase Notes as principal for resale.

          The Notes are being sold pursuant to a
Distribution Agreement between the Company and the
Agents, dated February 26, 1996 (the "Distribution
Agreement").  The Notes are to be issued as a new
series of senior notes under the Company's Indenture to
Liberty Bank and Trust Company of Tulsa, National
Association, as trustee (the "Trustee"), dated as of
February 1, 1996, as supplemented and as the same may
from time to time be amended or supplemented (the
"Indenture").  Until the Release Date (as defined in
the Indenture), the Notes will be secured as to payment
of principal and interest by one or more  series of
First Mortgage Bonds issued, pledged and delivered by
the Company to the Trustee.  A Registration Statement
(the "Registration Statement," which term shall include
any additional registration statements filed in
connection with the Notes as provided in the
introductory paragraphs of the Distribution Agreement)
with respect to the Notes has been filed with the
Securities and Exchange Commission (the "Commission").
The most recent Prospectus filed pursuant to Rule
424(b) is herein referred to as the "Prospectus."  A
pricing supplement with respect to the specific terms
of any Notes is herein referred to as a "Pricing
Supplement."  Chemical Bank will act as the paying
agent (the "Paying Agent") for the payment of principal
of and premium, if any, and interest on the Notes and
will perform as the Paying Agent, unless otherwise
specified, the other duties specified herein.  In
addition, Chemical Bank will act as the authenticating
agent (the "Authenticating Agent") under the Indenture.

          The Notes will either be issued (a) in
book-entry form and represented by one or more fully
registered Notes (each, a "Book-Entry Note") delivered
to Chemical Bank, as agent for The Depository Trust
Company ("DTC"), and recorded in the book-entry system
maintained by DTC, or (b) in certificated form
delivered to the purchaser thereof or a person
designated by such purchaser.  Except in the limited
circumstances described in the Prospectus or a Pricing
Supplement, owners of beneficial interests in Notes
issued in book-entry form will not be entitled to
physical delivery of Notes in certificated form equal
in principal amount to their respective beneficial
interests.

          General procedures relating to the issuance
of all Notes are set forth in Part I hereof.
Additionally, Notes issued in book-entry form will be
issued in accordance with the procedures set forth in
Part II hereof and Notes issued in certificated form
will be issued in accordance with the procedures set
forth in Part III hereof.  Capitalized terms used
herein that are not otherwise defined shall have the
meanings ascribed thereto in the Indenture or the
Notes, as the case may be.  As used herein, the term
"Prospectus" refers to the most recent prospectus which
has been prepared by the Company for use by the Agents
in connection with the offering of the Notes.

          To the extent the procedures set forth below
conflict with the provisions of the Notes, the
Indenture or the Distribution Agreement, the relevant
provisions of the Notes, the Indenture and the
Distribution Agreement shall control.

  PART II:  PROCEDURES FOR NOTES ISSUED IN BOOK-ENTRY
                         FORM
                           
                           
          In connection with the qualification of Notes
issued in book-entry form for eligibility in the
book-entry system maintained by DTC, the Paying Agent
will perform the custodial, document control and
administrative functions described below, in accordance
with its respective obligations under a Letter of
Representation from the Company and the Paying Agent to
DTC and a Medium-Term Note Certificate Agreement
between the Paying Agent and DTC (the "Certificate
Agreement"), and its obligations as a participant in
DTC, including DTC's Same-Day Funds Settlement System
("SDFS").

Issuance:                All Notes issued in book-entry form
                         having the same original issue date,
                         interest rate, and stated maturity
                         will be represented initially by a
                         single global security in fully
                         registered form without coupons
                         (each, a "Book-Entry Note").
                         
                         Each Book-Entry Note will be dated
                         and issued as of the date of its
                         authentication by the Authenticating
                         Agent.  Each Book-Entry Note will
                         bear an interest accrual date, which
                         will be (a) with respect to an
                         original Book-Entry Note (or any
                         portion thereof), its original issue
                         date and (b) with respect to any Book-
                         Entry Note (or portion thereof)
                         issued subsequently upon exchange of
                         a Book-Entry Note or in lieu of a
                         destroyed, lost or stolen Book-Entry
                         Note, the most recent interest
                         payment date to which interest has
                         been paid or duly provided for on the
                         predecessor Book-Entry Note or Notes
                         (or if no such payment or provision
                         has been made, the original issue
                         date of the predecessor Book-Entry
                         Note or Notes), regardless of the
                         date of authentication of such
                         subsequently issued Book-Entry Note.
                         No Book-Entry Note shall represent
                         any Note issued in certificated form.

Identification:          Prior to the commencement of the
                         program, the Company has arranged
                         with the CUSIP Service Bureau of
                         Standard & Poor's Corporation (the
                         "CUSIP Service Bureau") for the
                         reservation of a series consisting of
                         approximately 900 CUSIP numbers which
                         have been reserved for and relating
                         to Book-Entry Notes and the Company
                         has directed the Paying Agent to give
                         DTC a written list of such CUSIP
                         numbers.  The Paying Agent will
                         assign CUSIP numbers to Book-Entry
                         Notes as described below under
                         Settlement Procedure B.  DTC will
                         notify the CUSIP Service Bureau
                         periodically of the CUSIP numbers
                         that the Paying Agent has assigned to
                         Book-Entry Notes.

                         The Paying Agent will notify the
                         Company at any time when fewer than
                         50 of the reserved CUSIP numbers
                         remain unassigned to Book-Entry
                         Notes, and, if it deems necessary,
                         the Company will reserve additional
                         CUSIP numbers for assignment to Book-
                         Entry Notes.  Upon obtaining such
                         additional CUSIP numbers, the Company
                         will deliver a list of such
                         additional numbers to the Paying
                         Agent and DTC.
                         
Registration:            Each Book-Entry Note will be
                         registered in the name of Cede & Co.,
                         as nominee for DTC, on the register
                         maintained by the Trustee under the
                         Indenture.  The beneficial owner of a
                         Note issued in book-entry form (i.e.,
                         an owner of a beneficial interest in
                         a Book-Entry Note) (or one or more
                         indirect participants in DTC
                         designated by such owner) will
                         designate one or more participants in
                         DTC (with respect to such Note issued
                         in book-entry form, the
                         "Participants") to act as agent for
                         such beneficial owner in connection
                         with the book-entry system maintained
                         by DTC, and DTC will record in
                         book-entry form, in accordance with
                         instructions provided by such
                         Participants, a credit balance with
                         respect to such Note issued in
                         book-entry form in the account of
                         such Participants.  The ownership
                         interest of such beneficial owner in
                         such Note issued in book-entry form
                         will be recorded through the records
                         of such Participants or through the
                         separate records of such Participants
                         and one or more indirect participants
                         in DTC.
                         
Transfers:               Transfers of a Book-Entry Note will
                         be accomplished by book entries made
                         by DTC and, in turn, by Participants
                         (and in certain cases, one or more
                         indirect participants in DTC) acting
                         on behalf of beneficial transferors
                         and transferees of such Book-Entry
                         Note.
                         
Exchanges:               The Paying Agent may deliver to DTC
                         and the CUSIP Service Bureau at any
                         time a written notice specifying (a)
                         the CUSIP numbers of two or more Book-
                         Entry Notes outstanding on such date
                         that represent Book-Entry Notes
                         having the same terms (other than
                         original issue dates) and for which
                         interest has been paid to the same
                         date; (b) a date, occurring at least
                         30 days after such written notice is
                         delivered and at least 30 days before
                         the next interest payment date for
                         the related Notes issued in
                         book-entry form, on which such
                         Book-Entry Notes shall be exchanged
                         for a single replacement Book-Entry
                         Note; and (c) a new CUSIP number,
                         obtained from the Paying Agent, to be
                         assigned to such replacement
                         Book-Entry Note.  Upon receipt of
                         such a notice, DTC will send to its
                         participants (including the Paying
                         Agent) a written reorganization
                         notice to the effect that such
                         exchange will occur on such date.
                         Prior to the specified exchange date,
                         the Paying Agent will deliver to the
                         CUSIP Service Bureau written notice
                         setting forth such exchange date and
                         the new CUSIP number and stating
                         that, as of such exchange date, the
                         CUSIP numbers of the Book-Entry Notes
                         to be exchanged will no longer be
                         valid.  On the specified exchange
                         date, the Paying Agent will exchange
                         such Book-Entry Notes for a single
                         Book-Entry Note bearing the new CUSIP
                         numbers and the CUSIP number of the
                         exchanged Book-Entry Notes will, in
                         accordance with CUSIP Service Bureau
                         procedures, be canceled and not
                         immediately reassigned.

Denominations:           Notes issued in book-entry form will
                         be issued in denominations of $1,000
                         and any larger denomination which is
                         an integral multiple of $1,000.

Interest:                General.  Interest on each Note
                         issued in book-entry form will accrue
                         from the most recent interest payment
                         date to which interest has been paid
                         or duly provided for, or if no such
                         payment or provision has been made,
                         the original issue date of the
                         Book-Entry Note representing such
                         Note.  Each payment of interest on a
                         Note issued in book-entry form will
                         include interest accrued through the
                         day preceding, as the case may be,
                         the interest payment date or
                         maturity.  Interest payable at
                         maturity of a Note issued in
                         book-entry form will be payable to
                         the Person to whom the principal of
                         such Note is payable.  DTC will
                         arrange for each pending deposit
                         message described under Settlement
                         Procedure C below to be transmitted
                         to Standard & Poor's, which will use
                         the information in the message to
                         include certain terms of the related
                         Book-Entry Note in the appropriate
                         daily bond report published by
                         Standard & Poor's.
                         
                         Interest Payment Dates.  Interest
                         payments will be made on each
                         interest payment date commencing with
                         the first interest payment date
                         following the original issue date,
                         provided, however, that the first
                         payment of interest on any Book-Entry
                         Senior Note originally issued between
                         a regular record date and an interest
                         payment date will occur on the
                         interest payment date following the
                         next regular record date.
                         
                         Interest payments on Notes issued in
                         book-entry form will be made
                         semiannually on the dates specified
                         in the Pricing Supplement and at
                         maturity unless such day is not a
                         Business Day, in which case such
                         payment will be made on the next
                         Business Day.

  and Interest:          after each regular record date, the
                         Paying Agent will deliver to the
                         Company and DTC a written notice
                         specifying by CUSIP number the amount
                         of interest to be paid on each Book-
                         Entry Note on the following interest
                         payment date (other than an interest
                         payment date coinciding with
                         maturity) and the total of such
                         amounts.  DTC will confirm the amount
                         payable on each Book-Entry Note on
                         such interest payment date by
                         reference to the daily bond reports
                         published by Standard & Poor's
                         Corporation.  On such interest
                         payment date, the Company will pay to
                         the Paying Agent and the Paying Agent
                         in turn will pay to DTC, such total
                         amount of interest due (other than at
                         maturity), at the times and in the
                         manner set forth below under "Manner
                         of Payment."

                         the first Business Day of each month
                         in which principal and/or interest is
                         to be paid, the Paying Agent will
                         deliver to the Company and DTC a

                         and premium, if any, to be paid on
                         each Book-Entry Note maturing either
                         at stated maturity or on a redemption
                         date in the following month.  The
                         Paying Agent, the Company and DTC

                         Book-Entry Note is not timely paid to
                         the Participants with respect to such
                         Note by the beneficial purchaser
                         thereof (or a person, including an
                         indirect participant in DTC, acting
                         on behalf of such purchaser), such

                         related Agent may enter SDFS deliver
                         orders through DTC's Participant

                         entered pursuant to Settlement
                         Procedures H and I, respectively.
                         Thereafter, the Paying Agent will
                         deliver the withdrawal message and
                         take the related actions described in
                         the preceding paragraph.  If such
                         failure shall have occurred for any
                         reason other than default by the
                         applicable Agent to perform its
                         obligations hereunder or under the
                         Distribution Agreement, the Company
                         will reimburse such Agent on an
                         equitable basis for its loss of the
                         use of funds during the period when
                         the funds were credited to the
                         account of the Company.
                         
                         Notwithstanding the foregoing, upon
                         any failure to settle with respect to
                         a Book-Entry Note, DTC may take any
                         actions in accordance with its SDFS
                         operating procedures then in effect.
                         In the event of a failure to settle
                         with respect to a Note that was to
                         have been represented by a Book-Entry

                         issuance of a Book-Entry Note

                         will make appropriate entries in its
                         records.

Interest:                Each Note will bear interest in

                         issue date of a Note for the first
                         interest period and on the most
                         recent interest payment date to which
                         interest has been paid for all
                         subsequent interest periods.  Each
                         payment of interest shall include
                         interest accrued to, but excluding,
                         the date of such payment.

                         Nothing herein should be deemed to
                         require the Paying Agent to risk or
                         expend its own funds in connection
                         with any payment to the Company, or
                         the Agents, or DTC, or any
                         Noteholder, it being understood by
                         all parties that payments made by the
                         Paying Agent shall be made solely to
                         the extent that funds are provided to

                         case may be, and no interest shall
                         accrue for the period from and after
                         such interest payment date or
                         maturity.

                         required by applicable law, but shall
                         be relieved from any such
                         responsibility if it acts in good

tenor signed by such Holders in Person or by agent duly appointed
in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or
instruments are delivered to the Trustee and, where it is hereby
expressly required, to the Company.  Such instrument or
instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the
Holders signing such instrument or instruments.  Proof of
execution of any such instrument or of a writing appointing any
such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 601 hereof) conclusive in favor of the
Trustee and the Company, if made in the manner provided in this
Section 104.

          Without limiting the generality of the foregoing,

including a Depositary that is a Holder of a Global Security, may
make, give or take, by a proxy, or proxies, duly appointed in
writing, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in this Indenture to be
made, given or taken by Holders, and a Depositary that is a

the beneficial owners of interests in any such Global Security
through such Depositary's standing instructions and customary
practices.

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

          (c)  The ownership of Securities shall be proved by the
Security Register.

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

          (e)  The Company may set any day as the record date for
the purpose of determining the Holders of Outstanding Securities
of any series entitled to make any request or demand, or give any
authorization, direction, notice, consent or waiver, or take any
other action, provided or permitted by this Indenture to be made,
given or taken by Holders of Securities of such series.

          With regard to any record date set pursuant to this
paragraph, the Holders of Outstanding Securities of the relevant
series on such record date (or their duly appointed agents), and
only such Persons, shall be entitled to take relevant action,
whether or not such Holders remain Holders after such record
date.  With regard to any action that may be taken hereunder only
by Holders of a requisite principal amount of Outstanding
Securities of any series (or their duly appointed agents) and for
which a record date is set pursuant to this paragraph, the
Company may, at its option, set an expiration date after which no
such action purported to be taken by any Holder shall be
effective hereunder unless taken on or prior to such expiration
date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date (or their duly
appointed agents).  On or prior to any expiration date set
pursuant to this paragraph, the Company may, on one or more
occasions at its option, extend such expiration date to any later
date.  Nothing in this paragraph shall prevent any Holder (or any
duly appointed agent thereof) from taking, at any time, any action 
contrary to or different from, any action previously taken, or 
purported to have been taken, hereunder by such Holder, in which 
event the Company may set a record date in respect thereof pursuant 
to this paragraph.  Notwithstanding the foregoing or the Trust Indenture
Act, the Company shall not set a record date for, and the
provisions of this paragraph shall not apply with respect to, any
action to be taken by Holders pursuant to Section 501, 502 or 512
hereof.

     Upon receipt by the Trustee of notice of any default
described in Section 501 hereof, any declaration of acceleration,
or any rescission and annulment of any such declaration, pursuant
to Section 502 hereof or of any direction in accordance with
Section 512 hereof, a record date shall automatically and without
any other action by any Person be set for the purpose of
determining the Holders of Outstanding Securities of the series
entitled to join in such notice, declaration, or rescission and
annulment, or direction, as the case may be, which record date
shall be the close of business on the day the Trustee receives
such notice, declaration, rescission and annulment or direction,
as the case may be.  The Holders of Outstanding Securities of
such series on such record date (or their duly appointed agent),
and only such Persons, shall be entitled to join in such notice,
declaration, rescission and annulment, or direction, as the case
may be, whether or not such Holders remain Holders after such
record date; provided that, unless such notice, declaration,
rescission and annulment, or direction, as the case may be, shall
have become effective by virtue of Holders of the requisite
principal amount of Outstanding Securities of such series on such
record date (or their duly appointed agents) having joined
therein on or prior to the 90th day after such record date, such
notice of default, declaration, or rescission and annulment or
direction given or made by the Holders, as the case may be, shall
automatically and without any action by any Person be canceled
and of no further effect.  Nothing in this paragraph shall
prevent a Holder (or a duly appointed agent thereof) from giving,
before or after the expiration of such 90-day period, a notice of
default, a declaration of acceleration, a rescission and
annulment of a declaration of acceleration or a direction in
accordance with Section 512 hereof, contrary to or different
from, or, after the expiration of such period, identical to, a
previously given notice, declaration, rescission and annulment,
or direction, as the case may be, that has been canceled pursuant
to the proviso to the preceding sentence, in which event a new
record date in respect thereof shall be set pursuant to this
paragraph.

SECTION 105.  Notices, Etc., to Trustee and Company.

          Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or
permitted by this Indenture to be made upon, given or furnished

     Trustee or by the Company shall be sufficient for every
     purpose hereunder if made, given, furnished or filed in
     writing to or with the Trustee at its Corporate Trust
     Office, or

          (2)  the Company by the Trustee or by any Holder shall
     be sufficient for every purpose hereunder (unless otherwise

     principal office specified in the first paragraph of this
     instrument or at any other address previously furnished in
     writing to the Trustee by the Company.

SECTION 106.  Notice to Holders; Waiver.

          Where this Indenture provides for notice to Holders of

first-class postage prepaid, to each Holder affected by such
event, at his address as it appears in the Security Register, not
later than the latest date, and not earlier than the earliest
date, prescribed for the giving of such notice.  In any case
where notice to Holders is given by mail, neither the failure to
mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice
with respect to other Holders.  Where this Indenture provides for
notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such
notice.  Waivers of notice by Holders shall be filed with the

the validity of any action taken in reliance upon such waiver.

service or by reason of any other cause it shall be impracticable
to give such notice by mail, then such notification as shall be
made at the direction of the Company in a manner reasonably
calculated, to the extent practicable under the circumstances, to
provide prompt notice shall constitute a sufficient notification
for every purpose hereunder.

provision which is required or deemed to be included in this
Indenture by any of the provisions of the Trust Indenture Act,
the provision or requirement of the Trust Indenture Act shall
control.  If any provision of this Indenture modifies or excludes
any provision of the Trust Indenture Act that may be so modified
or excluded, such provision of the Trust Indenture Act shall be
deemed to apply to this Indenture as so modified or excluded, as
the case may be.

York.

SECTION 113.  Legal Holidays.

          In any case where any Interest Payment Date, Redemption
Date or Stated Maturity of any Security shall not be a Business

interest, if any, or principal (and premium, if any) need not be
made at such Place of Payment on such date, but may be made on
the next succeeding Business Day at such Place of Payment with
the same force and effect as if made on the Interest Payment Date
or Redemption Date, or at the Stated Maturity, provided that no
interest shall accrue for the period from and after such Interest

     price or prices at which and the terms and conditions upon
     which Securities of the series shall be redeemed, repaid or
     purchased, in whole or in part, pursuant to such obligation;

         (15)  if the Securities of the series shall be issued in
     whole or in part in the form of one or more Global
     Securities, (i) whether beneficial owners of interests in
     any such Global Security may exchange such interests for
     Securities of such series of like tenor and of authorized
     form and denomination and the circumstances under which any
     such changes may occur, if other than in the manner provided
     in Section 305 hereof and (ii) the Depositary for such
     Global Security or Securities;

          (16)  if prior to the Release Date, the designation of
     the series of Senior Note Mortgage Bonds being delivered to

     any; and

          (17)  any other terms of the series (which terms shall
     not be inconsistent with the provisions of this Indenture),
     including, without limitation, any terms required or
     appropriate to establish one or more series of medium-term
     notes.

          All Securities of any one series shall be substantially
identical except as to denomination and except as may otherwise
be provided in or pursuant to the Board Resolution referred to
above and set forth in the Officers' Certificate referred to
above or in any such indenture supplemental hereto.

          If any of the terms of the series, including the form
of Security of such series, are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record
of such action shall be certified by the Secretary or an
Assistant Secretary or other authorized officer of the Company,
and delivered to the Trustee at or prior to the delivery of the
Company Order contemplated by Section 303 hereof for the
authentication and delivery of such series of Securities.

SECTION 302.  Denominations.

          The Securities of each series shall be issuable in
registered form without coupons, except as otherwise expressly
provided in a supplemental indenture hereto, in such
denominations as shall be specified as contemplated by Section
301 hereof.  In the absence of any such provisions with respect
to the Securities of any series, the Securities of such series
shall be issuable in denominations of $1,000 and any integral
multiple thereof.

SECTION 303.  Execution, Authentication, Delivery and Dating.

          The Securities shall be executed on behalf of the
Company by its Chief Executive Officer, its President or one of
its Vice Presidents or its Treasurer under its corporate seal
reproduced thereon, and which need not be attested.  The
Securities of any series shall be executed by such additional
officer, if any, as shall be specified pursuant to Section 301
hereof.  The signature of any of these officers on the Securities
may be manual or facsimile.

          Securities bearing the manual or facsimile signature of
any individual who was at any time the proper officer of the
Company shall bind the Company, notwithstanding that such
individual has ceased to hold such office prior to the
authentication and delivery of such Securities or did not hold
such office at the date of authentication of such Securities.

          At any time and from time to time after the execution
and delivery of this Indenture, the Company may deliver
Securities of any series executed by the Company to the Trustee
for authentication, together with (i) a Company Order for the
authentication and delivery of such Securities, (ii) an Officers'
Certificate stating that (x) the Company is not, and upon the
authentication by the Trustee of the series of Securities, will
not be in default under any of the terms or covenants contained
in the Indenture, (y) all conditions that must be met by the
Company to issue Securities under the Indenture have been met,
and (z) if prior to the Release Date, the series of Senior Note
Mortgage Bonds being delivered to the Trustee meets the
requirements of Section 1310 hereof, (iii) if prior to the
Release Date, a certificate of an Expert meeting the requirements
of Section 1306(a) hereof, and (iv) if prior to the Release Date,
a series of Senior Note Mortgage Bonds meeting the requirements
of Section 1309 hereof, and the Trustee in accordance with the
Company Order shall authenticate and deliver such Securities.  If
the form or terms of the Securities of the series have been
established in or pursuant to one or more Board Resolutions as
permitted by Sections 201 and 301 hereof, in authenticating such
Securities, and accepting the additional responsibilities under
this Indenture in relation to such Securities, the Trustee shall
be entitled to receive, and (subject to Section 601 hereof) shall
be fully protected in relying upon, an Opinion of Counsel
stating,

          (a)  if the form of such Securities has been
     established by or pursuant to Board Resolution as permitted
     by Section 201 hereof, that such form has been established
     in conformity with the provisions of this Indenture;

          (b)  if the terms of such Securities have been
     established by or pursuant to Board Resolution as permitted
     by Section 301 hereof, that such terms have been established
     in conformity with the provisions of this Indenture;

          (c)  that such Securities, when authenticated and
     delivered by the Trustee and issued by the Company in the
     manner and subject to any conditions specified in such
     Opinion of Counsel, will constitute valid and legally
     binding obligations of the Company, enforceable in
     accordance with their terms, except as may be limited by
     bankruptcy, insolvency, reorganization, moratorium,
     fraudulent conveyance or transfer or other similar laws
     relating to or affecting the rights of creditors generally
     and except as the enforceability thereof is subject to the
     application of general principles of equity (regardless of
     whether considered in a proceeding in equity or at law),
     including, without limitation, (i) the possible
     unavailability of specific performance, injunctive relief or
     any other equitable remedy and (ii) concepts of materiality,
     reasonableness, good faith and fair dealing;

          (d) if prior to the Release Date, that the Senior Note
     Mortgage Bonds to be delivered to the Trustee in connection
     with the issuance of such series of Securities have been duly 
     authorized, and that such Senior Note Mortgage Bonds, when 
     authenticated and delivered by the First Mortgage Trustee and 
     issued by the  Company in accordance with the terms of the First 
     Mortgage Indenture, will constitute valid and legally binding
     obligations of the Company, enforceable in accordance with
     their terms, except as may be limited by bankruptcy,
     insolvency, reorganization, moratorium, fraudulent
     conveyance or transfer or other similar laws relating to or
     affecting the rights of creditors generally and except as
     the enforceability thereof is subject to the application of
     general principles of equity (regardless of whether
     considered in a proceeding in equity or at law), including,
     without limitation, (i) the possible unavailability of
     specific performance, injunctive relief or any other
     equitable remedy and (ii) concepts of materiality,
     reasonableness, good faith and fair dealing, and except as
     enforcement of remedial and procedural provisions thereof
     may be limited by state laws affecting the remedies for the
     enforcement of the security provided for in the First
     Mortgage Indenture; and that such Senior Note Mortgage Bonds
     will be entitled to the benefit of the First Mortgage
     Indenture, equally and ratably, with all other First
     Mortgage Bonds outstanding thereunder, except as to sinking
     fund provisions; and

          (e) if prior to the Release Date, that the First
     Mortgage Indenture and any required financing statements
     have been duly filed and recorded in all places where such
     filing or recording is necessary for the perfection or
     preservation of the lien of the First Mortgage Indenture,
     and the First Mortgage Indenture constitutes a valid and
     perfected first lien upon the property purported to be
     covered thereby, subject only to permissible encumbrances
     (as defined in the First Mortgage Indenture).

If such form or terms have been so established, the Trustee shall
not be required to authenticate such Securities if the issue of
such Securities pursuant to this Indenture will affect the
Trustee's own rights, duties, protections or immunities under the
Securities and this Indenture or otherwise in a manner which is
not reasonably acceptable to the Trustee.

          Notwithstanding the provisions of Section 301 hereof
and of the preceding paragraph, if all Securities of a series are
not to be originally issued at one time, it shall not be
necessary to deliver the Board Resolution, the Officers'
Certificate, or an indenture supplemental hereto otherwise
required pursuant to Section 301 hereof or the Company Order, the
Officers' Certificate, the certificate of an Expert, the Senior
Note Mortgage Bonds and the Opinion of Counsel otherwise required
pursuant to such preceding paragraph at or prior to the time of
authentication of each Security of such series if such documents
are delivered at or prior to the time of authentication upon
original issuance of the first Security of such series to be
issued.  If all of the Securities of a series are not
authenticated and issued at one time, for each issuance of
Securities after the initial issuance of Securities, the Company
shall be required only to deliver to the Trustee the Security
executed by the Company together with a Company Order to the
Trustee to authenticate such Security and to deliver such
Security in accordance with the instructions specified by such
Company Order.  Any such Company Order shall constitute a
representation and warranty by the Company that the statements
made in the Officers' Certificate delivered to the Trustee prior
to the authentication and issuance of the first Security of such 
series are true and correct on the date thereof as if made on and 
as of the date thereof.

          Each Security shall be dated the date of its
authentication.

          No Security shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there
appears on such Security a certificate of authentication
substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence,
that such Security has been duly authenticated and delivered
hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold
by the Company, and the Company shall deliver such Security to
the Trustee for cancellation as provided in Section 309 hereof
together with a written statement (which need not comply with
Section 102 hereof and need not be accompanied by an Opinion of
Counsel) stating that such Security has never been issued and
sold by the Company, for all purposes of this Indenture such
Security shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits
of this Indenture.

SECTION 304.  Temporary Securities.

          Pending the preparation of definitive Securities of any
series, the Company may execute, and upon Company Order the
Trustee shall authenticate and deliver, temporary Securities
which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially
of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officer or officers
executing such Securities may determine, as evidenced by their
execution of such Securities.

          If temporary Securities of any series are issued, the
Company will cause definitive Securities of that series to be
prepared without unreasonable delay.  After the preparation of
definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of
Payment for that series, without charge to the Holder.  Upon
surrender for cancellation of any one or more temporary
Securities of any series the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a
like principal amount of definitive Securities of the same series
and of like tenor of authorized denominations.  Until so
exchanged the temporary Securities of any series shall in all
respects be entitled to the same benefits under this Indenture as
definitive Securities of such series.

SECTION 305.   Registration, Registration of Transfer and
               Exchange.

          The Company shall cause to be kept at the Corporate
Trust Office of the Trustee a register (the register maintained
in such office and in any other office or agency of the Company
in a Place of Payment being herein sometimes collectively
referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall
provide for the registration of Securities and of transfers of
Securities. The Trustee is hereby appointed "Security Registrar" for the
purpose of registering Securities and transfers of Securities as
herein provided.

          Upon surrender for registration of transfer of any
Security of any series at the office or agency in a Place of
Payment for that series, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities
of the same series, of any authorized denominations and of a like
aggregate principal amount and tenor.

          At the option of the Holder, any Security or Securities
of any series, other than a Global Security, may be exchanged for
other Securities of the same series, of any authorized
denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at such office
or agency.  Whenever any Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

          All Securities issued upon any registration of transfer
or exchange of Securities shall be the valid obligations of the
Company, evidencing the same debt, and entitled to the same
benefits under this Indenture, as the Securities surrendered upon
such registration of transfer or exchange.

          Every Security presented or surrendered for
registration of transfer or for exchange shall (if so required by
the Company or the Trustee) be duly endorsed, or be accompanied
by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed, by the Holder
thereof or his attorney duly authorized in writing.

          No service charge shall be made to the Holder for any
registration of transfer or exchange of Securities, but the
Company may require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities,
other than exchanges pursuant to Sections 304, 906 or 1107 hereof
not involving any transfer.

          The Company shall not be required (i) to issue,
register the transfer of or exchange Securities of any series
during a period beginning at the opening of business 15 days
before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section
1103 hereof and ending at the close of business on the day of
such mailing, or (ii) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except
the unredeemed portion of any Security being redeemed in part.

          The provisions of this Section 305 are, with respect to
any Global Security, subject to Section 311 hereof.

SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

          If any mutilated Security is surrendered to the
Trustee, the Company shall execute and the Trustee shall
authenticate and deliver in
exchange therefor a new Security of the same series and of like
tenor and principal amount and bearing a number not
contemporaneously outstanding.

          If there shall be delivered to the Company and the
Trustee (i) evidence to their satisfaction of the destruction,
loss or theft of any Security and (ii) such security or indemnity
as may be required by them to save each of them and any agent of
either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a
bona fide purchaser, the Company shall execute and upon its
request the Trustee shall authenticate and deliver, in lieu of
any such destroyed, lost or stolen Security, a new Security of
the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen
Security has become or is about to become due and payable, the
Company in its discretion may, instead of issuing a new Security,
pay such Security.

          Upon the issuance of any new Security under this
Section 306, the Company may require the payment of a sum
sufficient to cover any tax or other governmental charge that may
be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

          Every new Security of any series issued pursuant to
this Section 306 in lieu of any destroyed, lost or stolen
Security shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally
and proportionately with any and all other Securities of that
series duly issued hereunder.

          The provisions of this Section 306 are exclusive and
shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities.

SECTION 307.  Payment of Interest; Interest Rights Preserved.

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

          Any interest on any Security of any series which is
payable, but is not punctually paid or duly provided for, on any
Interest Payment Date (herein called "Defaulted Interest") shall
forthwith cease to be payable to the Holder on the relevant
Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (1) or (2) below:

          (1)  The Company may elect to make payment of any
     Defaulted Interest to the Persons in whose names the
     Securities of such series (or their respective Predecessor
     Securities) are registered at the close of business on a
     Special Record Date for the payment of such Defaulted
     Interest, which shall be fixed in the following manner.  The
     Company shall notify the Trustee in writing of the amount of
     Defaulted Interest proposed to be paid on each Security of
     such series and the date of the proposed payment, and at the
     same time the Company shall deposit with the Trustee an
     amount of money equal to the aggregate amount proposed to be
     paid in respect of such Defaulted Interest or shall make
     arrangements satisfactory to the Trustee for such deposit
     prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons
     entitled to such Defaulted Interest as in this Clause
     provided.  Thereupon the Trustee shall fix a Special Record
     Date for the payment of such Defaulted Interest which shall
     be not more than 15 days and not less than 10 days prior to
     the date of the proposed payment and not less than 10 days
     after the receipt by the Trustee of the notice of the
     proposed payment.  The Trustee shall promptly notify the
     Company of such Special Record Date and, in the name and at
     the expense of the Company, shall cause notice of the
     proposed payment of such Defaulted Interest and the Special
     Record Date therefor to be mailed, first-class postage
     prepaid, to each Holder of Securities of such series at his
     address as it appears in the Security Register, not less
     than 10 days prior to such Special Record Date.  Notice of
     the proposed payment of such Defaulted Interest and the
     Special Record Date therefor having been so mailed, such
     Defaulted Interest shall be paid to the Persons in whose
     names the Securities of such series (or their respective
     Predecessor Securities) are registered at the close of
     business on such Special Record Date and shall no longer be
     payable pursuant to the following Clause (2).

          (2)  The Company may make payment of any Defaulted
     Interest on the Securities of any series in any other lawful
     manner not inconsistent with the requirements of any
     securities exchange on which such Securities may be listed,
     and upon such notice as may be required by such exchange,
     if, after notice given by the Company to the Trustee of the
     proposed payment pursuant to this Clause, such manner of
     payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section
307, each Security delivered under this Indenture upon
registration of transfer of or in exchange for or in lieu of any
other Security shall carry the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Security.
SECTION 308.  Persons Deemed Owners.

          Prior to due presentment of a Security for registration
of transfer, the Company, the Trustee and any agent of the
Company or the Trustee may treat the Person in whose name such
Security is registered as the owner of such Security for the
purpose of receiving payment of principal of (and premium, if
any) and (subject to Section 307 hereof) interest, if any, on
such Security and for all other purposes whatsoever, whether or
not such Security be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.  All such payments so made to
any such person, or upon such person's order, shall be valid,
and, to the extent of the sums so paid, effectual to satisfy and
discharge the liability for moneys payable upon any such
Security.

          No holder of any beneficial interest in any Global
Security held on its behalf by a Depositary shall have any rights
under this Indenture with respect to such Global Security, and
such Depositary may be treated by the Company, the Trustee, and
any agent of the Corporation or the Trustee as the owner of such
Global Security for all purposes whatsoever.  Notwithstanding the
foregoing, nothing herein shall impair, as between a Depositary
and such holders of beneficial interests, the operation of
customary practices governing the exercise of the rights of the
Depositary as holder of any Security.

SECTION 309.  Cancellation.

          All Securities surrendered for payment, redemption,
registration of transfer or exchange or for credit against any
sinking fund payment shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be
promptly canceled by it.  The Company may at any time deliver to
the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Securities so
delivered shall be promptly canceled by the Trustee.  No
Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section 309, except
as expressly permitted by this Indenture.  All canceled
Securities held by the Trustee shall be disposed of as directed
by a Company Order.

SECTION 310.  Computation of Interest.

          Except as otherwise specified as contemplated by
Section 301 hereof for Securities of any series, interest, if
any, on the Securities of each series shall be computed on the
basis of a 360-day year of twelve 30-day months.

SECTION 311.  Global Securities.

          If the Company shall establish pursuant to Section 301
hereof that the Securities of a particular series are to be
issued in the form of a Global Security, then the Company shall
execute and the Trustee shall, in accordance with Section 303
hereof, authenticate and deliver, a Global Security or Securities
which (i) shall represent, and shall be denominated in an
aggregate amount equal to the aggregate principal amount of, all
of the Outstanding Securities of such series, (ii) shall be
registered in the name of the Depositary or its nominee, (iii)
shall be delivered by the Trustee to the Depositary or pursuant
to the Depositary's instruction and (iv) shall bear a legend
substantially to the following effect:

          "This Security is a Global Security within the meaning
     of the Indenture hereinafter referred to and is registered
     in the name of a Depositary or a nominee of a Depositary.
     This Security is exchangeable for Securities registered in
     the name of a person other than the Depositary or its
     nominee only in the limited circumstances described in the
     Indenture, and no transfer of this Security (other than a
     transfer of this Security as a whole by the Depositary to a
     nominee of the Depositary or by a nominee of the Depositary
     to the Depositary or another nominee of the Depositary) may
     be registered except in limited circumstances.

          Unless this Global Security is presented by an
     authorized representative of the Depositary to the Company
     or its agent for registration of transfer, exchange or
     payment, and any definitive Security is issued in the name
     of [Cede & Co.] or in such other name as is requested by an
     authorized representative of the Depositary (and any payment
     is made to [Cede & Co.] or to such other entity as is
     requested by an authorized representative of the
     Depositary), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR
     VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL in as
     much as the registered owner hereof, [Cede & Co.], has an
     interest herein."

          Notwithstanding the provisions of Section 305 hereof,
the Global Security of a series may be transferred, in whole but
not in part and in the manner provided in Section 305 hereof,
only to another nominee of the Depositary for such series, or to
a successor Depositary for such series selected or approved by
the Company or to a nominee of such successor Depositary.

          If (i) at any time the Depositary for a series of
Securities notifies the Company that it is unwilling or unable to
continue as Depositary for such series or if at any time the
Depositary for such series shall no longer be registered or in
good standing under the Exchange Act, or other applicable statute
or regulation and a successor Depositary for such series is not
appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such condition, as the
case may be or (ii) there shall have occurred and be continuing
after any applicable grace periods an Event of Default with
respect to the Securities for a series, then in each such case,
this Section 311 shall no longer be applicable to the Securities
of such series and the Company will execute, and subject to
Section 305 hereof, the Trustee will authenticate and deliver
Securities of such series in definitive registered form without
coupons, in authorized denominations, and in an aggregate
principal amount equal to the principal amount of the Global
Securities of such series in exchange for such Global Securities.
In addition, the Company may at any time determine that the
Securities of any series shall no longer be represented by Global
Securities and that the provisions of this Section 311 shall no
longer apply to the Securities of such series.  In such event the
Company will execute and subject to Section 305 hereof, the
Trustee, upon receipt of an Officers' Certificate evidencing such
determination by the Company, will authenticate and deliver
Securities of such series in definitive registered form without
coupons, in authorized denominations, and in an aggregate
principal amount equal to the principal amount of the Global
Securities of such series in exchange for such Global Securities.
Upon the exchange of the Global Securities for such Securities in
definitive registered form without coupons, in authorized
denominations, the Global Securities shall be canceled by the
Trustee.  Such Securities in definitive registered form issued in
exchange for the Global Securities pursuant to this Section 311,
shall be registered in such names and in such authorized
denominations as the Depositary, pursuant to the instructions
from its direct or indirect participants or otherwise, shall
instruct the Trustee.  The Trustee shall deliver Securities to
the Depositary for delivery to the persons in whose names such
Securities are so registered.

SECTION 312.  Payment of Securities.

          The Trustee shall receive the Senior Note Mortgage
Bonds from the Company as provided in this Indenture and shall
hold the Senior Note Mortgage Bonds, and any and all sums payable
thereon or with respect thereto or realized therefrom, in trust
for the benefit of the Holders of the Securities, as herein
provided.  Subject to Article Five hereof, all payments made by
the Company to the Trustee on a series of Senior Note Mortgage
Bonds shall be applied by the Trustee to pay, when due, principal
of, premium, if any, and interest on the related series of
Securities and, to the extent so applied, shall satisfy the
Company's obligations on such Securities.  Notwithstanding the
foregoing, the Company's obligation to make payments of principal
of, premium, if any, and interest on any series of Senior Note
Mortgage Bonds shall be fully satisfied by making timely payments
of principal of, premium, if any, and interest on the related
series of Securities.

required to be deposited for the purpose for which such U.S.
Government Obligations or money was deposited or received.  This
provision shall not authorize the sale by the Trustee of any U.S.
Government Obligations held under this Indenture.

          (f)  the Company has delivered to the Trustee an
     Opinion of Counsel to the effect that such provision would
     not cause any Outstanding Securities of such series then
     listed on any national securities exchange to be delisted as
     a result thereof;

          (g)  no Event of Default or event which with notice or
     lapse of time would become an Event of Default (including by

     Board Resolution delivered to the Trustee on or prior to the
     date of deposit of such money or U.S. Government
     Obligations, and such Board Resolution shall be accompanied
     by an irrevocable Company Request that the Trustee give
     notice of such redemption in the name and at the expense of
     the Company not less than 30 nor more than 60 days prior to
     such Redemption Date in accordance with Section 1104 hereof;
     and

          (j)  the Company has delivered to the Trustee an

              Mortgage Bonds.

          (a)  If any series of Securities are deemed paid and
discharged pursuant to this Article Four, the obligation of the
Company to make payment with respect to the principal of and
premium, if any, and interest on the related series of Senior

in any manner.

          (c)  Upon the satisfaction and discharge of this
Indenture, the Trustee shall at the request of the Company return

     been included in this Indenture solely for the benefit of
     any series of Securities other than that series), and
     continuance of such default or breach for a period of 90
     days after there has been given, by registered or certified

     is a "Notice of Default" hereunder; or

          (5)  prior to the Release Date, a "default" as defined
     in the First Mortgage Indenture has occurred and is
     continuing, and the First Mortgage Trustee, the Company or
     Holders of at least 33% in aggregate principal amount of the
     Securities at the time outstanding shall have given written
     notice thereof to the Trustee; or

          (6)  the entry by a court having jurisdiction in the
     premises of (A) a decree or order for relief in respect of
     the Company in an involuntary case or proceeding under any
     applicable Federal or State bankruptcy, insolvency or other
     similar law or (B) a decree or order appointing a custodian,

          (7)  the commencement by the Company of a voluntary
     case or proceeding under any applicable Federal or State
     bankruptcy, insolvency or other similar law or of any other

     bankruptcy, insolvency or other similar law or to the
     commencement of any bankruptcy or insolvency case or
     proceeding against it, or the filing by it of a petition or
     answer or consent seeking relief under any applicable
     Federal or State law, or the consent by it to the filing of
     such petition or to the appointment of or taking possession
     by a custodian, receiver, liquidator, assignee, trustee,
     sequestrator or similar official of the Company or of any
     substantial part of its property, or the making by it of an
     assignment for the benefit of creditors, or the taking of
     corporate action by the Company in furtherance of any such
     action; or

          (8)  any other Event of Default provided in the
     supplemental indenture or provided in or pursuant to the
     Board Resolution under which such series of Securities is
     issued or in the form of Security for such series.

SECTION 502.  Acceleration of Maturity; Rescission and Annulment.

          If an Event of Default with respect to Securities of
any series at the time Outstanding described in paragraph (1),
(2), (3), (4), (5) or (8) of Section 501 hereof occurs and is
continuing, then in every such case the Trustee or the Holders of
not less than 33% in aggregate principal amount of the
Outstanding Securities of that series may declare the principal
amount (or, if any of the Securities of that series are Original
Issue Discount Securities, such portion of the principal amount
of such Securities as may be specified in the terms thereof) of
all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the
Trustee if given by Holders), and upon any such declaration such
principal amount (or specified amount) shall become immediately
due and payable upon the date which is 10 days after the date of
such notice.

          If an Event of Default described in paragraph (6) or
(7) of Section 501 hereof occurs and is continuing, then and in
every such case, the principal amount (or, if any Securities are
Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms thereof) of all the
Securities shall, without any notice to the Company or any other
act on the part of the Trustee or any Holder of the Securities,
become and be immediately due and payable.

          Upon the Securities being declared to be or becoming
due and payable, the Trustee can immediately file with the First
Mortgage Trustee a written demand for redemption of all Senior
Note Mortgage Bonds pursuant to the applicable provisions of the
supplemental indenture to the First Mortgage Indenture.

          At any time after such a declaration of acceleration
with respect to Securities of any series has been made and before
a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article provided
and prior to the mailing to the Trustee by the First Mortgage
Trustee of a firm, valid and unconditional notice to the Trustee
of the acceleration of all of the first mortgage bonds issued and
outstanding under the First Mortgage Indenture, the Holders of a
majority in principal amount of the Outstanding Securities of
that series, by written notice to the Company and the Trustee,
may rescind and annul such declaration and its consequences
(including if given the written demand for redemption of all
Senior Note Mortgage Bonds) if

          (1)  the Company has paid or deposited with the Trustee
     a sum sufficient to pay

                    (A)  all overdue interest, if any, on all
          Securities of that series,

                    (B)  the principal of (and premium, if any,
          on) any Securities of that series which have become due
          otherwise than by such declaration of acceleration and
          interest thereon at the rate or rates prescribed
          therefor in such Securities,

                    (C)  to the extent that payment of such
          interest is lawful, interest upon any overdue interest
          at the rate or rates prescribed therefor in such
          Securities, and

                    (D)  all sums paid or advanced by the Trustee
          hereunder and the reasonable compensation, expenses,
          disbursements and advances of the Trustee, its agents
          and counsel; and

          (2)  all Events of Default with respect to Securities
     of that series, other than the non-payment of the principal
     of and accrued interest on Securities of that series which
     have become due solely by such declaration of acceleration,
     have been cured or waived as provided in Section 513 hereof
     (including any defaults under the First Mortgage Indenture,
     as evidenced by notice thereof from the First Mortgage
     Trustee to the Trustee).

No such rescission shall affect any subsequent default or impair
any right consequent thereon.

          For all purposes under this Indenture, if a portion of
the principal of any Original Issue Discount Securities shall
have been accelerated and declared due and payable pursuant to
the provisions hereof, then, from and after such declaration,
unless such declaration has been rescinded and annulled, the
principal amount of such Original Issue Discount Securities shall
be deemed, for all purposes hereunder, to be such portion of the
principal thereof as shall be due and payable as a result of such
acceleration, and payment of such portion of the principal
thereof as shall be due and payable as a result of such
acceleration, together with interest, if any, thereon and all
other amounts owing thereunder, shall constitute payment in full
of such Original Issue Discount Securities.

SECTION 503.  Collection of Indebtedness and Suits for Enforcement 
                by Trustee.

          The Company covenants that if

          (1)  default is made in the payment of any interest on
     any Security when such interest becomes due and payable and
     such default continues for a period of 30 days, or

          (2)  default is made in the payment of the principal of
     (or premium, if any, on) any Security at the Maturity
     thereof,

the Company will, upon written demand of the Trustee, pay to it,
for the benefit of the Holders of such Securities, the whole
amount then due and payable on such Securities for principal (and
premium, if any) and interest, if any, and, to the extent that
payment of such interest shall be legally enforceable, interest
on any overdue principal (and premium, if any) and on any overdue
interest, at the rate or rates prescribed therefor in such
Securities, and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and
counsel.

          If the Company fails to pay such amounts forthwith upon
such demand, the Trustee, in its own name and as trustee of an
express trust, may institute a judicial proceeding for the
collection of the sums so due and unpaid (including, prior to the
Release Date, to exercise any rights to that end it may have as a
holder of Senior Note Mortgage Bonds), may prosecute such
proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and
collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any
other obligor upon such Securities, wherever situated.

          If any Event of Default with respect to Securities of
any series occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights (including,
prior to the Release Date, its rights as holder of the Senior
Note Mortgage Bonds) and the rights of the Holders of Securities
of such series by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any such
rights.

          The Trustee shall not be required to take notice or be
deemed to have notice of any Event of Default other than pursuant
to paragraphs (1), (2) or (3) of Section 501 of this Indenture,
unless the Trustee shall be specifically notified in writing of
such default by the Company, or by the Holders of a majority in
aggregate principal amount of Outstanding Securities.

SECTION 504.  Trustee May File Proofs of Claim.

          In case of the pendency of any receivership,
insolvency, liquidation, bankruptcy, reorganization, arrangement,
adjustment, composition or other judicial proceeding relative to
the Company or any other obligor upon the Securities or the
property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of
the Securities shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the
Trustee shall have made any demand on the Company for the payment
of overdue principal or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise,

          (i)  to file and prove a claim for the whole amount of
     principal (and premium, if any) and interest owing and
     unpaid in respect of the Securities and to file such other
     papers or documents as may be necessary or advisable in
     order to have the claims of the Trustee (including, prior to
     the Release Date, any claims of the Trustee as holder of
     Senior Note Mortgage Bonds and including any claim for the
     reasonable compensation, expenses, disbursements and
     advances of the Trustee, its agents and counsel) and of the
     Holders allowed in such judicial proceeding, and

         (ii)  to collect and receive any moneys or other
     property payable or deliverable on any such claims and to
     distribute the same;

and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall
consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 607 hereof.

          Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights
of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

SECTION 505.  Trustee May Enforce Claims Without Possession of
              Securities.

          All rights of action and claims under this Indenture or
the Securities may be prosecuted and enforced by the Trustee,
including, prior to the Release Date, its rights as holder of the
Senior Note Mortgage Bonds without the possession of any of the
Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall
be brought in its own name as trustee of an express trust, and
any recovery of judgment shall, after provision for the payment
of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of
which such judgment has been recovered.

SECTION 506.  Application of Money Collected.

          Any money collected by the Trustee pursuant to this
Article shall be applied in the following order with respect to
the Securities of any series, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account
of principal (or premium, if any) or interest, upon presentation
of the Securities and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

          FIRST:  To the payment of all amounts due the Trustee
     under Section 607 hereof;

          SECOND:  In case the principal and premium, if any, of
     the Securities of such series in respect of which moneys
     have been collected shall not have become and be then due
     and payable, to the payment of interest, if any, on the
     Securities of such series in default in the order of the
     maturity of the installments of such interest, with interest
     (to the extent that such interest has been collected by the
     Trustee and to the extent permitted by law) upon the overdue
     installments of interest at the rate prescribed therefor in
     such Securities, such payments to be made ratably to the
     Persons entitled thereto, without discrimination or
     preference;

          THIRD:  In case the principal or premium, if any, of
     the Securities of such series in respect of which moneys
     have been collected shall have become and shall be then due
     and payable, to the payment of the whole amount then owing
     and unpaid upon all the Securities of such series for
     principal and premium, if any, and interest, if any, with
     interest upon the overdue principal and premium, if any, and
     (to the extent that such interest has been collected by the
     Trustee and to the extent permitted by law) upon overdue
     installments of interest at the rate prescribed therefor in
     the Securities of such series; and in case such moneys shall
     be insufficient to pay in full the whole amount so due and
     unpaid upon the Securities of such series, then to the
     payment of such principal and any premium and interest,
     without preference or priority of principal over interest,
     or of interest over principal or premium, or of any
     installment of interest over any other installment of
     interest, or of any Security of such series over any other
     Security of such series, ratably to the aggregate of such
     principal and any premium and accrued and unpaid interest;
     and

          FOURTH:  To the payment of the remainder, if any, to
     the Company or any other Person lawfully entitled thereto.

SECTION 507.  Limitation on Suits.

          No Holder of any Security of any series shall have any
right to institute any proceeding, judicial or otherwise, with
respect to this Indenture, or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless

          (1)  such Holder has previously given written notice to
     the Trustee of a continuing Event of Default with respect to
     the Securities of that series;

          (2)  the Holders of not less than 33% in principal
     amount of the Outstanding Securities of that series shall
     have made written request to the Trustee to institute
     proceedings in respect of such Event of Default in its own
     name as Trustee hereunder;

          (3)  such Holder or Holders have offered to the Trustee
     reasonable indemnity against the costs, expenses and
     liabilities to be incurred in compliance with such request;

          (4)  the Trustee for 60 days after its receipt of such
     notice, request and offer of indemnity has failed to
     institute any such proceeding; and

          (5)  no direction inconsistent with such written
     request has been given to the Trustee during such 60-day
     period by the Holders of a majority in principal amount of
     the Outstanding Securities of that series;

it being understood and intended that no one or more of such
Holders shall have any right in any manner whatever by virtue of,
or by availing of, any provision of this Indenture to affect,
disturb or prejudice the rights of any other of such Holders, or
to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal
and ratable benefit of all such Holders.

SECTION 508.  Unconditional Right of Holders to Receive
              Principal, Premium and Interest.

          Notwithstanding any other provision in this Indenture,
the Holder of any Security shall have the right, which is
absolute and unconditional, to receive payment of the principal
of (and premium, if any) and (subject to Section 307 hereof)
interest, if any, on such Security on the Stated Maturity or
Maturities expressed in such Security (or, in the case of
redemption, on the Redemption Date) and to institute suit for the
enforcement of any such payment, and such rights shall not be
impaired without the consent of such Holder.

SECTION 509.  Restoration of Rights and Remedies.

          If the Trustee or any Holder has instituted any
proceeding to enforce any right or remedy under this Indenture
and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to
such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and
the Holders shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies
of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

SECTION 510.  Rights and Remedies Cumulative.

          Except as otherwise provided with respect to the
replacement or payment of mutilated, destroyed, lost or stolen
Securities in the last paragraph of Section 306 hereof, no right
or remedy herein conferred upon or reserved to the Trustee or to
the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in
equity or otherwise.  The assertion or employment of any right or
remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 511.  Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Holder of
any Securities to exercise any right or remedy accruing upon any
Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an
acquiescence therein.  Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders, as the case may be.

SECTION 512.  Control by Holders.

          The Holders of a majority in principal amount of the
Outstanding Securities of any series shall have the right to
direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust
or power conferred on the Trustee, with respect to the Securities
of such series, provided that

          (1)  such direction shall not be in conflict with any
     rule of law or with this Indenture,

          (2)  the Trustee may take any other action deemed
     proper by the Trustee which is not inconsistent with such
     direction, and

          (3)  the Trustee shall not determine that the action so
     directed would be unjustly prejudicial to Holders not taking
     part in such action.

SECTION 513.  Waiver of Past Defaults.

          The Holders of not less than a majority in aggregate
principal amount of the Outstanding Securities of any series may
on behalf of the Holders of all the Securities of such series
waive any past default hereunder with respect to such series and
its consequences, except a default

          (1)  in the payment of the principal of (or premium, if
     any) or interest, if any, on any Security of such series, or

          (2)  in respect of a covenant or provision hereof which
     under Article Nine cannot be modified or amended without the
     consent of the Holder of each Outstanding Security of such
     series affected.

          Upon any such waiver, such default shall cease to
exist, and any Event of Default arising therefrom shall be deemed
to have been cured, for every purpose of this Indenture; but no
such waiver shall extend to any subsequent or other default or
impair any right consequent thereon.

SECTION 514.  Undertaking for Costs.

          All parties to this Indenture agree, and each Holder of
any Security by his acceptance thereof shall be deemed to have
agreed, that any court may in its discretion require, 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 Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant
in such suit, having due regard to the merits and good faith of
the claims or defenses made by such party litigant; but the
provisions of this Section 514 shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder,
or group of Holders, holding in the aggregate more than 10% in
principal amount of the Outstanding Securities of any series, or
to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest, if
any, on any Security on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).


                          ARTICLE SIX

                          THE TRUSTEE

SECTION 601.  Certain Duties and Responsibilities.

          (a)  Except during the continuance of a default with
respect to the Securities of any series,

          (1)  the Trustee 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; and

          (2)  in the absence of bad faith on its part, the
     Trustee may conclusively rely, as to the truth of the
     statements and the correctness of the opinions expressed
     therein, upon certificates or opinions furnished to the
     Trustee and conforming to the requirements of this
     Indenture; but in the case of any such certificates or
     opinions which by any provision hereof are specifically
     required to be furnished to the Trustee, the Trustee shall
     examine the same to determine whether or not they conform to
     the requirements of this Indenture.

          (b)  In case a default has occurred and is continuing,
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.

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

          (1)  this Subsection shall not be construed to limit
     the effect of Subsection (a) of this Section 601;

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

          (3)  the Trustee shall not be liable with respect to
     any action taken or omitted to be taken by it in good faith
     in accordance with the direction of the Holders of a
     majority in principal amount of the Outstanding Securities
     of any series, determined as provided in Section 512 hereof,
     relating to the time, method and place of conducting any
     proceeding for any remedy available to the Trustee, or
     exercising any trust or power conferred upon the Trustee,
     under this Indenture with respect to the Securities of such
     series; and

          (4)  no provision of this Indenture shall 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 any of its rights or
     powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against
     such risk or liability is not reasonably assured to it.

          (d)  Whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee
shall be subject to the provisions of this Section 601.  The
permissive right of the Trustee to do things enumerated in this
Indenture shall not be construed as a duty and it shall not be
answerable for other than its own negligent action, its own
negligent failure to act or its own willful misconduct.

SECTION 602.  Notice of Defaults.

          Within 90 days after the occurrence of any default
hereunder with respect to the Securities of any series, the
Trustee shall transmit by mail to all Holders of Securities of
such series, as their names and addresses appear in the Security
Register, notice of such default hereunder known to the Trustee,
unless such default shall have been cured or waived; provided,
however, that, except in the case of a default in the payment of
the principal of (or premium, if any) or interest, if any, on any
Security of such series or in the payment of any sinking fund
installment with respect to Securities of such series, the
Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a
trust committee of directors or Responsible Officers of the
Trustee in good faith determine that the withholding of such
notice is in the interest of the Holders of Securities of such
series; and provided, further, that in the case of any default of
the character specified in Section 501(4) hereof with respect to
Securities of such series, no such notice to Holders shall be
given until at least 30 days after the occurrence thereof.  For
the purpose of this Section 602, the term "default" means any
event which is, or after notice or lapse of time or both would
become, an Event of Default with respect to Securities of such
series.

SECTION 603.  Certain Rights of Trustee.

          Subject to the provisions of Section 601 hereof:

          (a)  the Trustee may rely and shall be fully protected
in acting or refraining from acting upon any resolution,
certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, other
evidence of indebtedness or other paper or document believed by
it to be genuine and to have been signed or presented by the
proper party or parties;

          (b)  any request or direction of the Company mentioned
herein shall be sufficiently evidenced by a Company Request or
Company Order or as otherwise expressly provided herein and any
resolution of the Board of Directors may be sufficiently
evidenced by a Board Resolution;

          (c)  whenever in the administration of this Indenture
the Trustee shall deem it desirable that a matter be proved or
established prior to taking, suffering or omitting any action
hereunder, the Trustee (unless other evidence be herein
specifically prescribed) may, in the absence of bad faith on its
part, rely upon an Officers' Certificate;

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

          (e)  the Trustee shall be under no obligation to expend
or risk its own funds or to exercise, at the request or direction
of any of the Holders, any of the rights or powers vested in it
by this Indenture pursuant to this Indenture, unless such Holders
shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which might
be incurred by it in compliance with such request or direction;

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

          (g)  the Trustee may execute any of the trusts or
powers hereunder or perform any duties hereunder either directly
or by or through agents or attorneys and the Trustee shall not be
responsible for any misconduct or negligence on the part of any
agent or attorney appointed with due care by it hereunder.

SECTION 604.  Not Responsible for Recitals or Issuance of
              Securities.

          The recitals contained herein and in the Securities,
except the Trustee's certificates of authentication, shall be
taken as the statements of the Company, and neither the Trustee
nor any Authenticating Agent assumes any responsibility for their
correctness.  The Trustee makes no representations as to the
validity or sufficiency of this Indenture or of the Securities.
Neither the Trustee nor any Authenticating Agent shall be
accountable for the use or application by the Company of
Securities or the proceeds thereof.  The Trustee shall not be
responsible for doing or performing any thing or act which the
Company shall have covenanted to do or perform, or for any
compliance with any covenant by the Company, nor shall the
Trustee be bound to ascertain or inquire as to the performance of
any covenant, condition or agreement by the Company, but it may
require full information and advice in regard to any of the
foregoing.

SECTION 605.  May Hold Securities.

          The Trustee, any Authenticating Agent, any Paying
Agent, any Security Registrar or any other agent of the Company,
in its individual or any other capacity, may become the owner or
pledgee of Securities and, subject to Sections 608 and 613
hereof, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Authenticating Agent,
Paying Agent, Security Registrar or such other agent.

SECTION 606.  Money Held in Trust.

          Money held by the Trustee in trust hereunder need not
be segregated from other funds except to the extent required by
law.  The Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed with
the Company.

SECTION 607.  Compensation and Reimbursement.

          The Company agrees

          (1)  to pay to the Trustee from time to time such
     compensation as is agreed upon in writing, or, if no such
     agreement exists, reasonable compensation for all services
     rendered by it hereunder (which compensation shall not be
     limited by any provision of law in regard to the
     compensation of a trustee of an express trust), and shall
     have a lien therefor on any and all funds at any time held
     by it under this Indenture for such compensation;

          (2)  except as otherwise expressly provided herein, to
     reimburse the Trustee upon its request for all reasonable
     expenses, disbursements and advances incurred or made by the
     Trustee in accordance with any provision of this Indenture
     (including the reasonable compensation and the expenses and
     disbursements of its agents and counsel, which compensation,
     expenses and disbursements shall be set forth in sufficient
     detail), and shall have a lien therefor on any and all funds
     at any time held by it under this Indenture for such
     expenses and disbursements, except any such expense,
     disbursement or advance as may be attributable to its
     negligence or bad faith; and

          (3)  to indemnify the Trustee for, and to hold it
     harmless against, any loss, liability or expense incurred
     without negligence or bad faith on its part, arising out of
     or in connection with the acceptance or administration of
     the trust or trusts hereunder, including the costs and
     expenses of defending itself against any claim or liability
     in connection with the exercise or performance of any of its
     powers or duties hereunder.

SECTION 608.  Disqualification; Conflicting Interests.

          If the Trustee has or shall acquire a conflicting
interest within the meaning of the Trust Indenture Act, the
Trustee shall either eliminate such interest or resign, to the
extent and in the manner provided by, and subject to the
provisions of, the Trust Indenture Act and this Indenture
provided that, to the extent permitted by law, Liberty Bank and
Trust Company of Tulsa, National Association shall not be deemed
to have a conflicting interest for purposes of Section 310(b) of
the Trust Indenture Act because of its capacity as trustee under
the First Mortgage Indenture.  Nothing in this Indenture shall be
deemed to prohibit the Trustee or the Company from making any
application permitted pursuant to Section 310(b) of the Trust
Indenture Act.

SECTION 609.  Corporate Trustee Required; Eligibility.

          There shall at all times be a Trustee hereunder which
shall be eligible to act as trustee under the Trust Indenture Act
and which shall have a combined capital and surplus of at least
$50,000,000.  If the Trustee does not have an office in The City
of New York, the Trustee may appoint an agent in The City of New
York reasonably acceptable to the Company to conduct any
activities which the Trustee may be required under this Indenture
to conduct in The City of New York.  If the Trustee does not have
an office in The City of New York or has not appointed an agent
in The City of New York, the Trustee shall be a participant in
The Depository Trust Company and FAST distribution systems.  If
such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of a Federal,
State, or District of Columbia supervising or examining
authority, then for the purposes of this Section 609, the
combined capital and surplus of such corporation shall be deemed
to be its combined capital and surplus as set forth in its most
recent report of condition so published.  If at any time the
Trustee shall cease to be eligible in accordance with the
provisions of this Section 609, the Trustee shall resign
immediately in the manner and with the effect hereinafter
specified in this Article.

SECTION 610.   Resignation and Removal; Appointment of Successor
               Trustee.

          (a)  No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall
become effective until the acceptance of appointment by the
successor Trustee in accordance with the applicable requirements
of Section 611 hereof.

          (b)  The Trustee may resign at any time with respect to
the Securities of one or more series by giving written notice
thereof to the Company.  If the instrument of acceptance by a
successor Trustee required by Section 611 hereof shall not have
been delivered to the Trustee within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition
any court of competent jurisdiction for the appointment of a
successor Trustee with respect to the Securities of such series.

          (c)  The Trustee may be removed at any time with
respect to the Securities of any series by Act of the Holders of
a majority in principal amount of the Outstanding Securities of
such series, delivered to the Trustee and to the Company.

          (d)  If at any time:

          (1)  the Trustee shall fail to comply with Section
     310(b) of the Trust Indenture Act pursuant to Section 608
     hereof with respect to any series of Securities after
     written request therefor by the Company or by any Holder who
     has been a bona fide Holder of a Security for at least six
     months, or

          (2)  the Trustee shall cease to be eligible under
     Section 609 hereof and shall fail to resign after written
     request therefor by the Company or by any such Holder, or

          (3)  the Trustee shall become incapable of acting or
     shall be adjudged a bankrupt or insolvent or a receiver of
     the Trustee or of its property shall be appointed or any
     public officer shall take charge or control of the Trustee
     or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may
remove the Trustee with respect to all Securities, or (ii)
subject to Section 514 hereof, any Holder who has been a bona
fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with
respect to all Securities and the appointment of a successor
Trustee or Trustees.

          (e)  If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of
Trustee for any cause, with respect to the Securities of one or
more series, the Company, by a Board Resolution, shall promptly
appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the
Securities of one or more or all of such series and that at any
time there shall be only one Trustee with respect to the
Securities of any particular series) and shall comply with the
applicable requirements of Section 611 hereof.  If, within one
year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee with respect to
the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding
Securities of such series delivered to the Company and the
retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 611 hereof, become the
successor Trustee with respect to the Securities of such series and 
to that extent supersede the successor Trustee appointed by the Company. 
If no successor Trustee with respect to the Securities of any series 
shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 611 hereof, any
Holder who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

          (f)  The Company shall give notice of each resignation
and each removal of the Trustee with respect to the Securities of
any series and each appointment of a successor Trustee with
respect to the Securities of any series by mailing written notice
of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses
appear in the Security Register.  Each notice shall include the
name of the successor Trustee with respect to the Securities of
such series and the address of its Corporate Trust Office.

SECTION 611.  Acceptance of Appointment by Successor.

          (a)  In case of the appointment hereunder of a
successor Trustee with respect to all Securities, every such
successor Trustee so appointed shall execute, acknowledge and
deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or
removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance,
shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on the request of the
Company or the successor Trustee, such retiring Trustee shall,
upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer
and deliver to such successor Trustee all property and money held
by such retiring Trustee hereunder (including all right, title,
and interest in the Senior Note Mortgage Bonds).

          (b)  In case of the appointment hereunder of a
successor Trustee with respect to the Securities of one or more
(but not all) series, the Company, the retiring Trustee and each
successor Trustee with respect to the Securities of one or more
series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and
which (1) shall contain such provisions as shall be necessary or
desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of
the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee
relates, (2) if the retiring Trustee is not retiring with respect
to all Securities, shall contain such provisions as shall be
deemed necessary or desirable to confirm that all the rights,
powers, trusts and duties of the retiring Trustee with respect to
the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for
or facilitate the administration of the trusts hereunder by more
than one Trustee, it being understood that nothing herein or in
such supplemental indenture shall constitute such Trustees co-trustees
of the same trust and that each such Trustee shall be trustee of a trust
or trusts hereunder separate and apart from any trust or trusts
hereunder administered by any other such Trustee; and upon the
execution and delivery of such supplemental indenture the
resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor
Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of
the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee
relates; but, on request of the Company or any successor trustee,
such retiring Trustee shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such
retiring Trustee hereunder with respect to the Securities of that
or those series to which the appointment of such successor
Trustee relates.

          (c)  Upon request of any such successor Trustee, the
Company shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all
such rights, powers and trusts referred to in paragraph (a) or
(b) of this Section 611, as the case may be.

          (d)  No successor Trustee shall accept its appointment
unless at the time of such acceptance such successor Trustee
shall be qualified and eligible under this Article.

SECTION 612.  Merger, Conversion, Consolidation or Succession to
              Business.

          Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate
trust business of the Trustee, shall be the successor of the
Trustee hereunder, provided such corporation shall be otherwise
qualified and eligible under this Article, without the execution
or filing of any paper or any further act on the part of any of
the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office,
any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver
the Securities so authenticated with the same effect as if such
successor Trustee had itself authenticated such Securities.

SECTION 613.  Preferential Collection of Claims Against Company.

          (a)  Subject to Subsection (b) of this Section 613, if
the Trustee shall be or shall become a creditor, directly or
indirectly, secured or unsecured, of the Company within three
months prior to a default, as defined in Subsection (c) of this
Section 613, or subsequent to such a default, then, unless and
until such default shall be cured, the Trustee shall set apart
and hold in a special account for the benefit of the Trustee
individually, the Holders of the Securities and the holders of
other indenture securities, as defined in Subsection (c) of this
Section 613:

          (1)  an amount equal to any and all reductions in the
     amount due and owing upon any claim as such creditor in
     respect of principal or interest, effected after the
     beginning of such three-month period and valid as against
     the Company and its other creditors, except any such
     reduction resulting from the receipt or disposition of any
     property described in paragraph (2) of this Subsection, or
     from the exercise of any right of set-off which the Trustee
     could have exercised if a petition in bankruptcy had been
     filed by or against the Company upon the date of such
     default; and

          (2)  all property received by the Trustee in respect of
     any claims as such creditor, either as security therefor, or
     in satisfaction or composition thereof, or otherwise, after
     the beginning of such three-month period, or an amount equal
     to the proceeds of any such property, if disposed of,
     subject, however, to the rights, if any, of the Company and
     its other creditors in such property or such proceeds.

          Nothing herein contained, however, shall affect the
right of the Trustee:

          (A)  to retain for its own account (i) payments made on
     account of any such claim by any Person (other than the
     Company) who is liable thereon, and (ii) the proceeds of the
     bona fide sale of any such claim by the Trustee to a third
     Person, and (iii) distributions made in cash, securities or
     other property in respect of claims filed against the
     Company in bankruptcy or receivership or in proceedings for
     reorganization pursuant to the Federal Bankruptcy Act or
     applicable State law;

          (B)  to realize, for its own account, upon any property
     held by it as security for any such claim, if such property
     was so held prior to the beginning of such three-month
     period;

          (C)  to realize, for its own account, but only to the
     extent of the claim hereinafter mentioned, upon any property
     held by it as security for any such claim, if such claim was
     created after the beginning of such three-month period and
     such property was received as security therefor
     simultaneously with the creation thereof, and if the Trustee
     shall sustain the burden of proving that at the time such
     property was so received the Trustee had no reasonable cause
     to believe that a default, as defined in Subsection (c) of
     this Section 613, would occur within three months; or

          (D)  to receive payment on any claim referred to in
     paragraph (B) or (C), against the release of any property
     held as security for such claim as provided in paragraph (B)
     or (C), as the case may be, to the extent of the fair value
     of such property.

          For the purposes of paragraphs (B), (C) and (D),
property substituted after the beginning of such three-month
period for property held as security at the time of such
substitution shall, to the extent of the fair value of the
property released, have the same status as the property released,
and, to the extent that any claim referred to in any of such
paragraphs is created in renewal of or in substitution for or for
the purpose of repaying or refunding any pre-existing claim of
the Trustee as such creditor, such claim shall have the same
status as such pre-existing claim.

          If the Trustee shall be required to account, the funds
and property held in such special account and the proceeds
thereof shall be apportioned among the Trustee, the Holders and
the holders of other indenture securities in such manner that the
Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special
account and payments of dividends on claims filed against the
Company in bankruptcy or receivership or in proceedings for
reorganization pursuant to the Federal Bankruptcy Act or
applicable State law, the same percentage of their respective
claims, figured before crediting to the claim of the Trustee
anything on account of the receipt by it from the Company of the
funds and property in such special account and before crediting
to the respective claims of the Trustee and the Holders and the
holders of other indenture securities dividends on claims filed
against the Company in bankruptcy or receivership or in
proceedings for reorganization pursuant to the Federal Bankruptcy
Act or applicable State law, but after crediting thereon receipts
on account of the indebtedness represented by their respective
claims from all sources other than from such dividends and from
the funds and property so held in such special account.  As used
in this paragraph, with respect to any claim, the term
"dividends" shall include any distribution with respect to such
claim, in bankruptcy or receivership or proceedings for
reorganization pursuant to the Federal Bankruptcy Act or
applicable State law, whether such distribution is made in cash,
securities or other property, but shall not include any such
distribution with respect to the secured portion, if any, of such
claim.  The court in which such bankruptcy, receivership or
proceedings for reorganization is pending shall have jurisdiction
(i) to apportion among the Trustee, the Holders and the holders
of other indenture securities, in accordance with the provisions
of this paragraph, the funds and property held in such special
account and proceeds thereof, or (ii) in lieu of such
apportionment, in whole or in part, to give to the provisions of
this paragraph due consideration in determining the fairness of
the distributions to be made to the Trustee and the Holders and
the holders of other indenture securities with respect to their
respective claims, in which event it shall not be necessary to
liquidate or to appraise the value of any securities or other
property held in such special account or as security for any such
claim, or to make a specific allocation of such distributions as
between the secured and unsecured portions of such claims, or
otherwise to apply the provisions of this paragraph as a
mathematical formula.

          Any Trustee which has resigned or been removed after
the beginning of such three-month period shall be subject to the
provisions of this Subsection as though such resignation or
removal had not occurred.  If any Trustee has resigned or been
removed prior to the beginning of such three-month period, it
shall be subject to the provisions of this Subsection if and only
if the following conditions exist:

          (i)  the receipt of property or reduction of claim,
     which would have given rise to the obligation to account, if
     such Trustee had continued as Trustee, occurred after the
     beginning of such three-month period; and

         (ii)  such receipt of property or reduction of claim
     occurred within three months after such resignation or
     removal.

          (b)  There shall be excluded from the operation of
Subsection (a) of this Section 613 a creditor relationship
arising from:

          (1)  the ownership or acquisition of securities issued
     under any indenture, or any security or securities having a
     maturity of one year or more at the time of acquisition by
     the Trustee;

          (2)  advances authorized by a receivership or
     bankruptcy court of competent jurisdiction or by this
     Indenture, for the purpose of preserving any property which
     shall at any time be subject to the lien of this Indenture
     or of discharging tax liens or other prior liens or
     encumbrances thereon, if notice of such advances and of the
     circumstances surrounding the making thereof is given to the
     Holders at the time and in the manner provided in this
     Indenture;

          (3)  disbursements made in the ordinary course of
     business in the capacity of trustee under an indenture,
     transfer agent, registrar, custodian, paying agent, fiscal
     agent or depository, or other similar capacity;

          (4)  an indebtedness created as a result of services
     rendered or premises rented; or an indebtedness created as a
     result of goods or securities sold in a cash transaction, as
     defined in Subsection (c) of this Section 613;

          (5)  the ownership of stock or of other securities of a
     corporation organized under the provisions of Section 25(a)
     of the Federal Reserve Act, as amended, which is directly or
     indirectly a creditor of the Company; and

          (6)  the acquisition, ownership, acceptance or
     negotiation of any drafts, bills of exchange, acceptances or
     obligations which fall within the classification of
     self-liquidating paper, as defined in Subsection (c) of this
     Section 613.

          (c)  For the purposes of this Section 613 only:

                    (1)  the term "default" means any failure to
          make payment in full of the principal of or interest on
          any of the Securities or upon the other indenture
          securities when and as such principal or interest
          becomes due and payable;

                    (2)  the term "other indenture securities"
          means securities upon which the Company is an obligor
          (as defined in the Trust Indenture Act) outstanding
          under any other indenture (i) under which the Trustee
          is also trustee, (ii) which contains provisions
          substantially similar to the provisions of this Section
          613, and (iii) under which a default exists at the time
          of the apportionment of the funds and property held in
          such special account;

                    (3)  the term "cash transaction" means any
          transaction in which full payment for goods or
          securities sold is made within seven days after
          delivery of the goods or securities in currency or in
          checks or other orders drawn upon banks or bankers and
          payable upon demand;

                    (4)  the term "self-liquidating paper" means
          any draft, bill of exchange, acceptance or obligation
          which is made, drawn, negotiated or incurred by the
          Company for the purpose of financing the purchase,
          processing, manufacturing, shipment, storage or sale of
          goods, wares or merchandise and which is secured by
          documents evidencing title to, possession of, or a lien
          upon, the goods, wares or merchandise or the
          receivables or proceeds arising from the sale of the
          goods, wares or merchandise previously constituting the
          security, provided the security is received by the
          Trustee simultaneously with the creation of the
          creditor relationship with the Company arising from the
          making, drawing, negotiating or incurring of the draft,
          bill of exchange, acceptance or obligation;

                    (5)  the term "Company" means any obligor
          upon the Securities; and

                    (6)  the term "Federal Bankruptcy Act" means
          the Bankruptcy Code or Title 11 of the United States
          Code.

SECTION 614.  Authenticating Agents.

          From time to time the Trustee, in its sole discretion,
may appoint one or more Authenticating Agents with respect to one
or more series of Securities with power to act on the Trustee's
behalf and subject to its direction in the authentication and
delivery of Securities of such series or in connection with
transfers and exchanges under Sections 304, 305, 306, and 1107
hereof as fully to all intents and purposes as though the
Authenticating Agent had been expressly authorized by those
Sections of this Indenture to authenticate and deliver Securities
of such series.  For all purposes of this Indenture, the
authentication and delivery of Securities by an Authenticating
Agent pursuant to this Section 614 shall be deemed to be
authentication and delivery of such Securities "by the Trustee".
Each such Authenticating Agent shall be acceptable to the Company
and shall at all times be a corporation organized and doing
business under the laws of the United States, any State thereof
or the District of Columbia, authorized under such laws to
exercise corporate trust powers, having a combined capital and
surplus of at least $50,000,000 and  subject to supervision or
examination by Federal, State or District of Columbia authority.
If such corporation publishes reports of condition at least
annually pursuant to law or the requirements of such authority,
then for the purposes of this Section 614 the combined capital
and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent
report of condition so published.  If at any time an
Authenticating Agent shall cease to be eligible in accordance
with the provisions of this Section 614, such Authenticating
Agent shall resign immediately in the manner and with the effect
specified in this Section 614.

          Any corporation into which any Authenticating Agent may
be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation or to
which any Authenticating Agent shall be a party, or any
corporation succeeding to the corporate trust business of any
Authenticating Agent, shall be the successor of the
Authenticating Agent hereunder, if such successor corporation is
otherwise eligible under this Section 614, without the execution
or filing of any paper or any further act on the part of the
parties hereto or the Authenticating Agent or such successor
corporation.

          An Authenticating Agent may resign at any time by
giving written notice of resignation to the Trustee and to the
Company.  The Trustee may at any time terminate the agency of any
Authenticating Agent by giving written notice of termination to
such Authenticating Agent and to the Company.  Upon receiving
such a notice of resignation or upon such a termination, or in
case at any time any Authenticating Agent shall cease to be
eligible under this Section 614, the Trustee may appoint a
successor Authenticating Agent which shall be acceptable to the
Company and shall mail notice of such appointment to all Holders
of Securities of the series with respect to which such
Authenticating Agent will serve, as the names and addresses of
such Holders appear on the Security Register.  Any successor
Authenticating Agent, upon acceptance of its appointment
hereunder, shall become vested with all the rights, powers and
duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent.  No successor
Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 614.

          The Trustee agrees to pay to each Authenticating Agent
from time to time reasonable compensation for its services under
this Section 614, and the Trustee shall be entitled to be
reimbursed for such payments pursuant to Section 607 hereof.

          If an appointment with respect to one or more series of
Securities is made pursuant to this Section 614, the Securities
of such series may have endorsed thereon, in addition to the
Trustee's certificate of authentication, an alternate certificate
of authentication in the following form:

          This is one of the Securities of the series designated
herein referred to in the within-mentioned Indenture.


                              [NAME OF TRUSTEE],

                              __________________________________
                                           As Trustee


                              __________________________________
                                     As Authenticating Agent


                              __________________________________
                                       Authorized Officer


                         ARTICLE SEVEN

       HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

SECTION 701.  Company to Furnish Trustee Names and Addresses of
              Holders.

          The Company will furnish or cause to be furnished to
the Trustee with respect to the Securities of each series

          (a)  semi-annually, not later than 15 days after each
     Regular Record Date, or, in the case of any series of
     Securities on which semi-annual interest is not payable, not
     more than 15 days after such semi-annual dates as may be
     specified by the Trustee, a list, in such form as the
     Trustee may reasonably require, of the names and addresses
     of the Holders as of such Regular Record Date or semi-annual
     date, as the case may be, and

          (b)  at such other times as the Trustee may request in
     writing, within 30 days after the receipt by the Company of
     any such request, a list of similar form and content as of a
     date not more than 15 days prior to the time such list is
     furnished;

provided, however, that if and so long as the Trustee is Security
Registrar for any series of Securities, no such list shall be
required to be furnished with respect to any such series.

SECTION 702.  Preservation of Information; Communications to
              Holders.

          (a)  The Trustee shall preserve, in as current a form
as is reasonably practicable, the names and addresses of Holders
contained in the most recent list furnished to the Trustee as
provided in Section 701 hereof and the names and addresses of
Holders received by the Trustee in its capacity as Security
Registrar.  The Trustee may destroy any list furnished to it as
provided in Section 701 hereof upon receipt of a new list so
furnished.

          (b)  If three or more Holders (herein referred to as
"applicants") apply in writing to the Trustee, and furnish to the
Trustee reasonable proof that each such applicant has owned a
Security for a period of at least six months preceding the date
of such application, and such application states that the
applicants desire to communicate with other Holders with respect
to their rights under this Indenture or under the Securities and
is accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, then the
Trustee shall, within five business days after the receipt of
such application, at its election, either

          (i)  afford such applicants access to the information
     preserved at the time by the Trustee in accordance with
     Section 702(a) hereof, or

         (ii)  inform such applicants as to the approximate
     number of Holders whose names and addresses appear in the
     information preserved at the time by the Trustee in
     accordance with Section 702(a) hereof, and as to the
     approximate cost of mailing to such Holders the form of
     proxy or other communication, if any, specified in such
     application.

          If the Trustee shall elect not to afford such
applicants access to such information, the Trustee shall, upon
the written request of such applicants, mail to each Holder whose
name and address appear in the information preserved at the time
by the Trustee in accordance with Section 702(a) hereof a copy of
the form of proxy or other communication which is specified in
such request, with reasonable promptness after a tender to the
Trustee of the material to be mailed and of payment, or provision
for the payment, of the reasonable expenses of mailing, unless
within five days after such tender the Trustee shall mail to such
applicants and file with the Commission, together with a copy of
the material to be mailed, a written statement to the effect
that, in the opinion of the Trustee, such mailing would be
contrary to the best interest of the Holders or would be in
violation of applicable law.  Such written statement shall
specify the basis of such opinion.  If the Commission, after
opportunity for a hearing upon the objections specified in the
written statement so filed, shall enter an order refusing to
sustain any of such objections or if, after the entry of an order
sustaining one or more of such objections, the Commission shall
find, after notice and opportunity for hearing, that all the
objections so sustained have been met and shall enter an order so
declaring, the Trustee shall mail copies of such material to all
such Holders with reasonable promptness after the entry of such
order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to such applicants
respecting their application.

          (c)  Every Holder of Securities, by receiving and
holding the same, agrees with the Company and the Trustee that
neither the Company nor the Trustee nor any agent of either of
them shall be held accountable by reason of the disclosure of any
such information as to the names and addresses of the Holders in
accordance with Section 702(b) hereof, regardless of the source
from which such information was derived, and that the Trustee
shall not be held accountable by reason of mailing any material
pursuant to a request made under Section 702(b) hereof.

SECTION 703.  Reports by Trustee.

          (a)  Within 60 days after the first May 15 which occurs
not less than 60 days following the first date of issuance of
Securities of any series under this Indenture and within 60 days
after May 15 in every year thereafter, the Trustee shall transmit
by mail to all Holders, as their names and addresses appear in
the Security Register, a brief report dated as of such May 15
with respect to any of the following events which may have
occurred within the previous 12 months (but if no such event has
occurred within such period no report need be transmitted):

          (1)  any change to its eligibility under Section 609
     hereof and its qualifications under Section 608 hereof;

          (2)  the creation of or any material change to a
     relationship specified in Section 608 hereof;

          (3)  the character and amount of any advances (and if
     the Trustee elects so to state, the circumstances
     surrounding the making thereof) made by the Trustee (as
     such) which remain unpaid on the date of such report, and
     for the reimbursement of which it claims or may claim a lien
     or charge, prior to that of the Securities, on any property
     or funds held or collected by it as Trustee, except that the
     Trustee shall not be required (but may elect) to report such
     advances if such advances so remaining unpaid aggregate not
     more than 1/2 of 1% of the principal amount of the
     Securities Outstanding on the date of such report;

          (4)  any change to the amount, interest rate and
     maturity date of all other indebtedness owing by the Company
     (or by any other obligor on the Securities) to the Trustee
     in its individual capacity, on the date of such report, with
     a brief description of any property held as collateral
     security therefor, except an indebtedness based upon a
     creditor relationship arising in any manner described in
     Sections 613(b)(2), (3), (4) or (6) hereof;

          (5)  any change to the property and funds, if any,
     physically in the possession of the Trustee as such on the
     date of such report;

          (6)  any release, or release and substitution, of
     property subject to the lien of this Indenture (and the
     consideration therefor, if any) which it has not previously
     reported;

          (7)  any additional issue of Securities which the
     Trustee has not previously reported; and

          (8)  any action taken by the Trustee in the performance
     of its duties hereunder which it has not previously reported
     and which in its opinion materially affects the Securities,
     except action in respect of a default, notice of which has
     been or is to be withheld by the Trustee in accordance with
     Section 602 hereof.

          (b)  The Trustee shall transmit by mail to all Holders,
as their names and addresses appear in the Security Register, a
brief report with respect to (1) the release, or release and
substitution, of property subject to the lien of this Indenture
(and the consideration therefor, if any) unless the fair value of
such property, as set forth in the certificate required by
Section 1306 hereof, is less than 10% of the principal amount of
Securities outstanding at the time of such release, or release
and substitution, and (2) the character and amount of any
advances (and if the Trustee elects so to state, the
circumstances surrounding the making thereof) made by the Trustee
(as such) since the date of the last report transmitted pursuant
to Subsection (a) of this Section 703 (or if no such report has
yet been so transmitted, since the date of execution of this
instrument) for the reimbursement of which it claims or may claim
a lien or charge, prior to that of the Securities, on property or
funds held or collected by it as Trustee and which it has not
previously reported pursuant to this Subsection, except that the
Trustee shall not be required (but may elect) to report such
advances if such advances remaining unpaid at any time aggregate
10% or less of the principal amount of the Securities Outstanding
at such time, such report to be transmitted within 90 days after
such time.

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

SECTION 704.  Reports by Company.

          The Company shall:

          (1)  file with the Trustee, within 15 days after the
     Company is required to file the same with the Commission,
     copies of the annual reports and of the information,
     documents and other reports (or copies of such portions of
     any of the foregoing as the Commission may from time to time
     by rules and regulations prescribe) which the Company may be
     required to file with the Commission pursuant to Section 13
     or Section 15(d) of the Securities Exchange Act of 1934; or,
     if the Company is not required to file information,
     documents or reports pursuant to either of said Sections,
     then it shall file with the Trustee and the Commission, in
     accordance with rules and regulations prescribed from time
     to time by the Commission, such of the supplementary and
     periodic information, documents and reports which may be
     required pursuant to Section 13 of the Securities Exchange
     Act of 1934 in respect of a security listed and registered
     on a national securities exchange as may be prescribed from
     time to time in such rules and regulations;

          (2)  file with the Trustee and the Commission, in

     Company with the conditions and covenants of this Indenture
     as may be required from time to time by such rules and
     regulations; and

          (3)  transmit by mail to all Holders, as their names
     and addresses appear in the Security Register, within 30
     days after the filing thereof with the Trustee, such

and covenants under this Indenture and the Securities.


                          ARTICLE NINE

                    SUPPLEMENTAL INDENTURES

SECTION 901.  Supplemental Indentures without Consent of Holders.

          Without the consent of any Holders, the Company and the
Trustee, at any time and from time to time, may enter into one or
more indentures supplemental hereto, in form satisfactory to the
Trustee, for any of the following purposes:

          (1)  to evidence the succession of another corporation
     to the Company and the assumption by any such successor of
     the covenants of the Company herein and in the Securities;

          (2)  to add to the covenants of the Company for the
     benefit of the Holders of all or any series of Securities
     (and if such covenants are to be for the benefit of less
     than all series of Securities, stating that such covenants
     are expressly being included solely for the benefit of such
     series) or to surrender any right or power herein conferred
     upon the Company;

          (3)  to add any additional Events of Default;

          (4)  to add to or change any of the provisions of this
     Indenture to such extent as shall be necessary to permit or
     facilitate the issuance of Securities in bearer form,
     registrable or not registrable as to principal, and with or
     without interest coupons, or to facilitate the issuance of
     Securities in uncertificated form, or to permit or
     facilitate the issuance of extendible Securities;

          (5)  to change or eliminate any of the provisions of
     this Indenture, provided that any such change or elimination
     shall become effective only as to the Securities of any
     series created by such supplemental indenture and Securities
     of any series subsequently created to which such change or
     elimination is made applicable by the subsequent
     supplemental indenture creating such series;

          (6)  to secure the Securities;

          (7)  to establish the form or terms of Securities of
     any series as permitted by Sections 201 and 301 hereof;

          (8)  to evidence and provide for the acceptance of
     appointment hereunder by a successor Trustee with respect to
     the Securities of one or more series and to add to or change

     necessary to provide for or facilitate the administration of
     the trusts hereunder by more than one Trustee, pursuant to
     the requirements of Section 611(b) hereof;

          (9)  to provide for any rights of the Holders of
     Securities of any series to require the repurchase of
     Securities of such series by the Company;

         (10)  to cure any ambiguity, to correct or supplement
     any provision herein which may be inconsistent with any
     other provision herein, or to make any other provisions with
     respect to matters or questions arising under this
     Indenture, provided such action shall not adversely affect
     the interests of the Holders of Securities of any series in
     any material respect;

         (11)  after the Release Date, to amend this Indenture to
     eliminate any provisions related to the Senior Note Mortgage
     Bonds which are no longer applicable; or

         (12)  to modify, alter, amend or supplement this
     Indenture in any other respect which is not materially
     adverse to Holders, which does not involve a change
     described in clauses (1), (2) or (3) of Section 902 hereof
     and which, in the judgment of the Trustee, is not to the
     prejudice of the Trustee, in order to provide for the
     duties, responsibilities and compensation of the Trustee as
     a transfer agent in the event one registered Security of any
     series is issued in the aggregate principal amount of all
     Outstanding Securities of such series in which Holders will
     hold an interest.

SECTION 902.  Supplemental Indentures with Consent of Holders.

          With the consent of the Holders of a majority in
aggregate principal amount of the Outstanding Securities of all
series affected by such supplemental indenture (voting as one
class), by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by or pursuant to a Board
Resolution, and the Trustee may enter into an indenture or
indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the
rights of the Holders of Securities of such series under this
Indenture; provided, however, that no such supplemental indenture
shall, without the consent of the Holder of each Outstanding
Security affected thereby,

          (1)  change the Stated Maturity of the principal of, or
     any installment of principal of or interest, if any, on, any
     Security, or reduce the principal amount thereof or the rate
     of interest thereon or any premium payable upon the
     redemption thereof, or reduce the amount of the principal of
     an Original Issue Discount Security that would be due and
     payable upon a declaration of acceleration of the Maturity
     thereof pursuant to Section 502 hereof, or change any Place
     of Payment where, or the coin or currency in which, any
     Security or any premium or the interest thereon is payable,
     or impair the right to institute suit for the enforcement of
     any such payment on or after the Stated Maturity thereof
     (or, in the case of redemption, on or after the Redemption
     Date), or impair the interest hereunder of the Trustee in
     the Senior Note Mortgage Bonds, or prior to the Release
     Date, reduce the principal amount of any series of Senior
     Note Mortgage Bonds to an amount less than the principal
     amount of the related series of Securities or alter the
     payment provisions of such Senior Note Mortgage Bonds in a
     manner adverse to the Holders of the Securities, or

          (2)  reduce the percentage in principal amount of the
     Outstanding Securities of any series, the consent of whose
     Holders is required for any such supplemental indenture, or
     the consent of whose Holders is required for any waiver (of
     compliance with certain provisions of this Indenture or
     certain defaults hereunder and their consequences) provided
     for in this Indenture, or

          (3)  modify any of the provisions of this Section 902
     or Section 513 hereof, except to increase any such
     percentage or to provide that certain other provisions of
     this Indenture cannot be modified or waived without the
     consent of the Holder of each Outstanding Security affected
     thereby, provided, however, that this clause shall not be
     deemed to require the consent of any Holder with respect to
     changes in the references to "the Trustee" and concomitant
     changes in this Section 902, or the deletion of this
     proviso, in accordance with the requirements of Sections
     611(b) and 901(8) hereof.

A supplemental indenture which changes or eliminates any covenant
or other provision of this Indenture which has expressly been
included solely for the benefit of one or more particular series
of Securities, or which modifies the rights of the Holders of
Securities of such series with respect to such covenant or other
provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

          It shall not be necessary for any Act of Holders under
this Section 902 to approve the particular form of any proposed
supplemental indenture, but it shall be sufficient if such Act
shall approve the substance thereof.

SECTION 903.  Execution of Supplemental Indentures.

          In executing, or accepting the additional trusts
created by, any supplemental indenture permitted by this Article
or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and (subject
to Section 601 hereof) shall be fully protected in relying upon,
an Opinion 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 904.  Effect of Supplemental Indentures.

          Upon the execution of any supplemental indenture under
this Article, this Indenture shall be modified in accordance
therewith, and such supplemental indenture shall form a part of
this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

SECTION 905.  Conformity with Trust Indenture Act.

          Every supplemental indenture executed pursuant to this
Article shall conform to the requirements of the Trust Indenture
Act as then in effect.

SECTION 906.  Reference in Securities to Supplemental Indentures.

          Securities of any series authenticated and delivered
after the execution of any supplemental indenture pursuant to
this Article may, and shall if required by the Trustee, bear a
notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture.  If the Company
shall so determine, new Securities of any series so modified as
to conform, in the opinion of the Trustee and the Company, to any
such supplemental indenture may be prepared and executed by the
Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.


                          ARTICLE TEN

                           COVENANTS

SECTION 1001.  Payment of Principal, Premium and Interest.

          The Company covenants and agrees for the benefit of
each series of Securities that it will duly and punctually pay
the principal of (and premium, if any) and interest, if any, on
the Securities of that series in accordance with the terms of the
Securities and this Indenture.

SECTION 1002.  Maintenance of Office or Agency.

          The Company will maintain in each Place of Payment for
any series of Securities an office or agency where Securities of
that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the
Company in respect of the Securities of that series and this
Indenture may be served.  The Company will give prompt written
notice to the Trustee of the location, and any change in the
location, of such office or agency.  If at any time the Company
shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and, in such
event, the Trustee shall act as the Company's agent to receive
all such presentations, surrenders, notices and demands.

          The Company may also from time to time designate one or
more other offices or agencies where the Securities of one or
more series may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall
in any manner relieve the Company of its obligation to maintain
an office or agency in each Place of Payment for Securities of
any series for such purposes.  The Company will give prompt
written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other
office or agency.

SECTION 1003.  Money for Securities Payments to Be Held in Trust.

          If the Company shall at any time act as its own Paying
Agent with respect to any series of Securities, it will, on or
before each due date of the principal of (and premium, if any) or
interest, if any, on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay the principal (and
premium, if any) or interest, if any, so becoming due until such
sums shall be paid to such Persons or otherwise disposed of as
herein provided and will promptly notify the Trustee of its
action or failure so to act.

          Whenever the Company shall have one or more Paying
Agents for any series of Securities, it will, no later than 11:00
a.m., New York Time, on or prior to each due date of the
principal of (and premium, if any) or interest, if any, on any
Securities of that series, deposit with a Paying Agent a sum in
immediately available funds sufficient to pay the principal (and
premium, if any) or interest so becoming due, such sum to be held
in trust for the benefit of the Persons entitled to such
principal, premium or interest, and (unless such Paying Agent is
the Trustee) the Company will promptly notify the Trustee of its
failure so to act.

          The Company will cause each Paying Agent for any series
of Securities other than the Trustee to execute and deliver to
the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provisions of this Section 1003,
that such Paying Agent will:

          (1)  hold all sums held by it for the payment of the
     principal of (and premium, if any) or interest, if any, on
     Securities of that series in trust for the benefit of the
     Persons entitled thereto until such sums shall be paid to
     such Persons or otherwise disposed of as herein provided;

          (2)  give the Trustee notice of any default by the
     Company (or any other obligor upon the Securities of that
     series) in the making of any payment of principal (and
     premium, if any) or interest, if any, on the Securities of
     that series; and

          (3)  at any time during the continuance of any such
     default, upon the written request of the Trustee, forthwith
     pay to the Trustee all sums so held in trust by such Paying
     Agent.

          The Company may at any time, for the purpose of
obtaining the satisfaction and discharge of this Indenture or for
any other purpose, pay, or by Company Order direct any Paying
Agent to pay, to the Trustee all sums held in trust by the
Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by
the Company or such Paying Agent; and, upon such payment by any
Paying Agent to the Trustee, such Paying Agent shall be released
from all further liability with respect to such money.

          Any money deposited with the Trustee or any Paying
Agent, or then held by the Company, in trust for the payment of
the principal of (and premium, if any) or interest, if any, on
any Security of any series and remaining unclaimed for two years
after such principal (and premium, if any) or interest has become
due and payable shall be paid to the Company on Company Request,
or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security shall thereafter, as an
unsecured general creditor, look only to the Company for payment
thereof, and all liability of the Trustee or such Paying Agent
with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being
required to make any such repayment, shall at the written request
and expense of the Company cause to be published once, in a
newspaper published in the English language, customarily
published on each Business Day and of general circulation in [
] notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the
date of such publication, any unclaimed balance of such money
then remaining will be repaid to the Company.

SECTION 1004.  Corporate Existence.

          Subject to Article Eight, the Company will do or cause
to be done all things necessary to preserve and keep in full
force and effect its corporate existence and will use its best
efforts to do or cause to be done all things necessary to
preserve and keep in full force and effect its rights (charter
and statutory) and franchises; provided, however, that the
Company shall not be required to preserve any such right or
franchise if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the
business of the Company.

SECTION 1005.  Maintenance of Properties.

          The Company will cause all properties used or useful in
the conduct of its business or the business of any Subsidiary to
be maintained and kept in good condition, repair and working
order and supplied with all necessary equipment and will cause to
be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted
at all times; provided, however, that nothing in this Section
1005 shall prevent the Company from discontinuing the operation
or maintenance of any of such properties if such discontinuance
is, in the judgment of the Company, desirable in the conduct of
its business or the business of any Subsidiary.

SECTION 1006.  Maintenance of Insurance.

          The Company will maintain, and will cause each of its
Subsidiaries to maintain, with insurers the Company reasonably
believes to be financially sound and reputable, insurance deemed
adequate by the Company with respect to its properties and
business and the properties and business of its Subsidiaries
against loss or damage of the kinds customarily insured against
by corporations in the same or similar business.  Such insurance
may be subject to co-insurance, deductibility or similar clauses
which, in effect, result in self-insurance of certain losses,
provided that such self-insurance is in accord with the practices
of corporations in the same or similar business and adequate
insurance reserves are maintained in connection with such self-
insurance.

SECTION 1007.  Limitation on Liens.

          Nothing in this Indenture or in the Securities shall in
any way restrict or prevent the Company or any Subsidiary from
incurring any indebtedness; provided that if this covenant shall
be made applicable to the Securities of a particular series, the
Company covenants and agrees that it will not, nor will it permit
any Subsidiary to, issue, assume or guarantee any notes, bonds,
debentures or other similar evidences of indebtedness for money
borrowed ("Debt") secured by a Mortgage upon any property or
assets without effectively providing that the Outstanding
Securities to which this section shall have been made applicable
(together with, if the Company so determines, any other
indebtedness or obligation then existing or thereafter created
ranking equally with the Securities) shall be secured equally and
ratably with (or prior to) such Debt so long as such Debt shall
be so secured (provided, that for the purpose of providing such
equal and ratable security, the principal amount of Outstanding
Securities of any series of Original Issue Discount Securities
shall be such portion of the principal amount as may be specified
in the terms of that series), except that the foregoing
provisions shall not apply to:

          (a)  Mortgages in existence on the date of original
     issue of the Securities of any series to which this
     restriction is made applicable (including without limitation
     any obligations issued or incurred, or to be issued or
     incurred, under the First Mortgage Indenture);

          (b)  Mortgages created solely for the purpose of
     securing Debt incurred to finance, refinance or refund the
     purchase price or cost (including the cost of construction)
     of property or assets acquired after the date hereof (by
     purchase, construction or otherwise), or Mortgages in favor
     of guarantors of obligations or Debt representing, or
     incurred to finance, refinance or refund, such purchase
     price or cost, provided that no such Mortgage shall extend
     to or cover any property or assets other than the property
     or assets so acquired and improvements thereon (other than,
     in the case of Mortgages securing Debt incurred to finance
     construction or improvement costs, any theretofore
     unimproved real property on which the property so
     constructed, or the improvement, is located);

          (c)  Mortgages which secure only indebtedness owing by
     a Subsidiary to the Company, to one or more Subsidiaries or
     to the Company and one or more Subsidiaries;

          (d)  Mortgages on any property or assets acquired from
     a corporation which is merged with or into the Company or
     any Subsidiary, or any Mortgages on the property or assets
     of any Corporation or other entity existing at the time such
     Corporation or other entity becomes a Subsidiary and, in
     either such case, is not created as a result of or in
     connection with or in anticipation of any such transaction
     (unless such Mortgage was created to secure or provide for
     the payment of any part of the purchase price of such
     corporation);

          (e)  Any Mortgage on any property or assets existing at
     the time of acquisition thereof and which is not created as
     a result of or in connection with or in anticipation of such
     acquisition (unless such Mortgage was created to secure or
     provide for the payment of any part of the purchase price of
     such property or assets); or

          (f)  Any extension, renewal or replacement (or
     successive extensions, renewals or replacements), in whole
     or in part, of any Mortgage referred to in the foregoing
     clauses (a) through (e) or of any Debt secured thereby,
     provided that the principal amount of Debt so secured
     thereby shall not exceed the principal amount of Debt so
     secured at the time of such extension, renewal or
     replacement, and that such extension, renewal or replacement
     Mortgage shall be limited to all or part of substantially
     the same property which secured the Mortgage extended,
     renewed or replaced (plus improvements on or additions to
     such property).

          Notwithstanding the foregoing provisions of this

assume or guarantee Debt secured by Mortgages which would
otherwise be subject to the foregoing restrictions in an
aggregate principal amount which, together with the aggregate
outstanding principal amount of all other Debt of the Company and
its Subsidiaries which would otherwise be subject to the
foregoing restrictions (not including Debt permitted to be
secured under clauses (a) through (f)) hereof does not at the
time of issuance, assumption, or guarantee thereof exceed 10% of
Net Tangible Assets.

          The following types of transactions, among others,
shall not be deemed to create Debt secured by Mortgages:

          Mortgages required by any contract or statute in order
     to permit the Company or a Subsidiary to perform any
     contract or subcontract made by it with or at the request of
     a governmental entity or any department, agency or
     instrumentality thereof, or to secure partial, progress,
     advance or any other payments to the Company or any
     Subsidiary by a governmental entity or any department,
     agency or instrumentality thereof pursuant to the provisions
     of any contract or statute.

          The Company will deliver to the Trustee on or before
May 15 in each year, an Officers' Certificate stating that in the
course of the performance by each signer of his duties as an
officer of the Company he would normally have knowledge of any
default by the Company in the performance and observance of any
of the covenants contained in Sections 1001 to 1007 hereof,
stating whether or not he has knowledge of any such default and,
if so, specifying each such default of which such signer has

Release Date, the Company shall promptly notify the Trustee of
such event.

     Indenture and of any indenture supplemental to this
     Indenture but prior to the Release Date, an Opinion of

     financing or continuation statements have been properly
     recorded and filed so as to make effective and to perfect
     the security interest of the Trustee intended to be created
     by this Indenture for the benefit of the Holders from time
     to time of the Securities in the Senior Note Mortgage Bonds,
     and reciting the details of such action, or stating that, in
     the opinion of such counsel, no such action is necessary to
     perfect or make such security interest effective and stating

     succeeding March 1 to maintain, perfect and make such

     the opinion of such counsel no such action is necessary to

     succeeding March 1 to maintain, perfect and make such
     security interest effective.

          The Company may omit in any particular instance to
comply with any term, provision or condition set forth in
Sections 801 and 1004 to 1007 hereof, inclusive, with respect to
the Securities of any series if before the time for such
compliance the Holders of at least a majority in aggregate

                         ARTICLE ELEVEN

                    REDEMPTION OF SECURITIES

SECTION 1101.  Applicability of Article.

          Securities of any series which are redeemable before
their Stated Maturity shall be redeemable in accordance with
their terms and (except as otherwise specified as contemplated by
Section 301 hereof for Securities of any series) in accordance
with this Article Eleven.

SECTION 1102.  Election to Redeem; Notice to Trustee.

          The election of the Company to redeem any Securities
shall be authorized by a Board of Directors resolution and
evidenced by an Officers' Certificate.  In case of any redemption
at the election of the Company of less than all the Securities of
any series, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Securities of such
series to be redeemed.  In the case of any redemption of
Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere
in this Indenture, or pursuant to an election by the Company
which is subject to a condition specified in the terms of such
Securities or elsewhere in this Indenture, the Company shall
furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction or condition.

SECTION 1103.  Selection by Trustee of Securities to
               Be Redeemed.

          If less than all the Securities of any series are to be
redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by
the Trustee, from the Outstanding Securities of such series not
previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to the minimum
authorized denomination for Securities of that series or any
integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.

          Securities shall be excluded from eligibility for
selection for redemption if they are identified by registration
and certificate number in a written statement signed by an
authorized officer of the Company and delivered to the Security
Registrar at least 60 days prior to the Redemption Date as being
owned of record and beneficially by, and not pledged or
hypothecated by either (a) the Company or (b) an entity
specifically identified in such written statement which is an
Affiliate of the Company.

          The Trustee shall promptly notify the Company in
writing of the Securities selected for redemption and, in the
case of any Securities selected for partial redemption, the
principal amount thereof to be redeemed.

          For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of
Securities shall relate, in the case of any Securities redeemed
or to be redeemed only in part, to the portion of the principal
amount of such Securities which has been or is to be redeemed.

SECTION 1104.  Notice of Redemption.

          Notice of redemption shall be given by first-class
mail, postage prepaid, mailed not less than 30 nor more than 60
days prior to the Redemption Date, to each Holder of Securities
to be redeemed, at his address appearing in the Security
Register.

          All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

          (3)  if less than all the Outstanding Securities of any
     series are to be redeemed, the identification (and, in the
     case of partial redemption, the principal amounts) of the
     particular Securities to be redeemed,

          (4)  that on the Redemption Date the Redemption Price
     will become due and payable upon each such Security to be
     redeemed and, if applicable, that interest thereon will
     cease to accrue on and after said date,

          (5)  the place or places where such Securities are to
     be surrendered for payment of the Redemption Price, and

          (6)  that the redemption is for a sinking fund, if such
     is the case.

          Notice of redemption of Securities to be redeemed at
the election of the Company shall be given by the Company or, at
the Company's request, by the Trustee in the name and at the
expense of the Company.

SECTION 1105.  Deposit of Redemption Price.

          On or prior to any Redemption Date, the Company shall
deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in
trust as provided in Section 1003 hereof) an amount of money
sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities which are to be redeemed on that
date (to the extent that such amounts are not already on deposit
at such time in accordance with the provisions of Sections 401,
403 or 1010 hereof).

SECTION 1106.  Securities Payable on Redemption Date.

          Notice of redemption having been given as aforesaid,
the Securities so to be redeemed shall, on the Redemption Date,
become due and payable at the Redemption Price therein specified,
and from and after such date (unless the Company shall default in
the payment of the Redemption Price and accrued and unpaid
interest) such Securities shall cease to bear interest.  Upon
surrender of any such Security for redemption in accordance with
said notice, such Security shall be paid by the Company at the
Redemption Price, together with accrued and unpaid interest to
the Redemption Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one
or more Predecessor Securities, registered as such at the close
of business on the relevant Record Dates according to their terms
and the provisions of Section 307 hereof.

          If any Security called for redemption shall not be so
paid upon surrender thereof for redemption, the principal (and
premium, if any) shall, until paid, bear interest from the
Redemption Date at the rate prescribed therefor in the Security.

SECTION 1107.  Securities Redeemed in Part.

          Any Security (including any Global Security) which is
to be redeemed only in part shall be surrendered at a Place of
Payment therefor (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in
writing), and the Company shall execute, and the Trustee shall
authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of the same series,
of any authorized denomination as requested by such Holder, in
aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so
surrendered; provided, that if a Global Security is so
surrendered, the new Global Security shall be in a denomination
equal to the unredeemed portion of the principal of the Global
Security so surrendered.

                         ARTICLE TWELVE

                         SINKING FUNDS

SECTION 1201.  Applicability of Article.

          The provisions of this Article shall be applicable to
any sinking fund for the retirement of Securities of a series
except as otherwise specified as contemplated by Section 301
hereof for Securities of such series.

          The minimum amount of any sinking fund payment provided
for by the terms of Securities of any series is herein referred
to as a "mandatory sinking fund payment", and any payment in
excess of such minimum amount provided for by the terms of
Securities of any series is herein referred to as an "optional
sinking fund payment".  If provided for by the terms of
Securities of any series, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1202
hereof.  Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the
terms of Securities of such series.

SECTION 1202.  Satisfaction of Sinking Fund Payments with
               Securities.

          In lieu of making all or any part of any mandatory
sinking fund payment with respect to any series of Securities in
cash, the Company may at its option (a) deliver to the Trustee
Securities of such series theretofore purchased or otherwise
acquired (except upon redemption pursuant to the mandatory
sinking fund) by the Company or receive credit for Securities of
such series (not previously so credited) theretofore purchased or
otherwise acquired (except as aforesaid) by the Company and
delivered to the Trustee for cancellation pursuant to Section 309
hereof, (b) receive credit for optional sinking fund payments
(not previously so credited) made pursuant to this Section 1202,
or (c) receive credit for Securities of such series (not
previously so credited) redeemed by the Company through any
optional redemption provision contained in the terms of such
series.  Securities so delivered or credited shall be received or
credited by the Trustee at the sinking fund Redemption Price
specified in such Securities.

SECTION 1203.  Redemption of Securities for Sinking Fund.

          Not less than 60 days prior to each sinking fund
payment date for any series of Securities, the Company will
deliver to the Trustee an Officers' Certificate specifying (a)
the amount of the next ensuing sinking fund payment for that
series pursuant to the terms of that series, (b) whether or not
the Company intends to exercise its right, if any, to make an
optional sinking fund payment with respect to such series on the
next ensuing sinking fund payment date and, if so, the amount of
such optional sinking fund payment, and (c) the portion thereof,
if any, which is to be satisfied by payment of cash and the
portion thereof, if any, which is to be satisfied by delivering
and crediting Securities of that series pursuant to Section 1202
hereof, and will also deliver to the Trustee any Securities to be
so delivered.  Such written statement shall be irrevocable and
upon its receipt by the Trustee the Company shall become
unconditionally obligated to make all the cash payments or
payments therein referred to, if any, on or before the next
succeeding sinking fund payment date.  Failure of the Company, on
or before any such 60th day, to deliver such written statement
and Securities specified in this paragraph, if any, shall not
constitute a default but shall constitute, on and as of such
date, the irrevocable election of the Company (i) that the
mandatory sinking fund payment for such series due on the next
succeeding sinking fund payment date shall be paid entirely in
cash without the option to deliver or credit Securities of such
series in respect therefor and (ii) that the Company will make no
optional sinking fund payment with respect to such series as
provided in this Section 1203.

            Not less than 30 days before each such sinking fund
payment date the Trustee shall select the Securities to be
redeemed upon such sinking fund payment date in the manner
specified in Section 1103 hereof and cause notice of the
redemption thereof to be given in the name of and at the expense
of the Company in the manner provided in Section 1104 hereof.
Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated
in Sections 1105, 1106 and 1107 hereof.

          The Trustee shall not redeem or cause to be redeemed
any Security of a series with sinking fund moneys or mail any
notice of redemption of Securities of such series by operation of
the sinking fund during the continuance of a default in payment
of interest with respect to Securities of that series or an Event
of Default with respect to the Securities of that series except
that, where the mailing of notice of redemption of any Securities
shall theretofore have been made, the Trustee shall redeem or
cause to be redeemed such Securities, provided that it shall have
received from the Company a sum sufficient for such redemption.
Except as aforesaid, any moneys in the sinking fund for such
series at the time when any such default or Event of Default,
shall occur, and any moneys thereafter paid into the sinking
fund, shall, during the continuance of such default or Event of
Default, be deemed to have been collected under Article Five and
held for the payment of all such Securities.  In case such Event
of Default shall have been waived as provided in Section 513
hereof or the default or Event of Default cured on or before the
60th day preceding the sinking fund payment date, such moneys
shall thereafter be applied on the next succeeding sinking fund
payment date in accordance with this Section 1203 to the
redemption of such Securities.

          The Trustee, as a Holder of Senior Note Mortgage Bonds,
shall attend any meeting of bondholders under the First Mortgage
Indenture as to which it receives due notice, or, at its option,
shall deliver its proxy in connection therewith.  Either at such
meeting, or otherwise where consent of holders of first mortgage
bonds issued under the First Mortgage Indenture is sought without
a meeting, the Trustee shall vote all of the Senior Note Mortgage
Bonds held by it, or shall consent or withhold its consent with
respect thereto, as directed by the Holders of not less than a
majority in the aggregate principal amount of the outstanding
Securities; provided, however, the Trustee shall not vote as such
holder of any particular series of Senior Note Mortgage Bonds in
favor of, or give its consent to, any action which, in the
Trustee's opinion, would materially adversely affect such series
of Senior Note Mortgage Bonds in a manner not shared generally by
all other Senior Note Mortgage Bonds, except upon notification by
the Trustee to the Holders of the related series of Securities of
such proposal and consent thereto of the Holders of not less than
a majority in aggregate principal amount of the outstanding
Securities of such series.

        SECTION 1304.  No Transfer of Senior Note Mortgage Bonds; Exception.

          Except as required to effect an assignment to a
successor trustee under this Indenture or pursuant to Section

issue stop transfer instructions to the First Mortgage Trustee
and any transfer agent under the First Mortgage Indenture to
effect compliance with this Section 1304.

        SECTION 1305.  Delivery to the Company of All Senior Note Mortgage
                       Bonds.

          When the obligation of the Company to make payment with
respect to the principal of and premium, if any, and interest on
the Senior Note Mortgage Bonds shall be satisfied or deemed
satisfied pursuant to Section 401 or Section 1310 hereof, the
Trustee shall, upon written request of the Company and receipt of

(if such certificate is then required by Section 1306(b) hereof),
deliver to the Company without charge therefor all of the Senior
Note Mortgage Bonds, together with such appropriate instruments
of transfer or release as may be reasonably requested by the

          SECTION 1306.  Fair Value Certificate.

          (a) Upon the delivery by the Company to the Trustee of

Note Mortgage Bonds and of this Indenture, (2) stating the
principal amount of such Senior Note Mortgage Bonds so delivered,
the stated interest rate (or method of calculation of interest)
of such Senior Note Mortgage Bonds and the stated maturity date

equal to or exceeds (A) $25,000 and (B) 1% of the principal
amount of the Securities outstanding at the date of delivery of
such Senior Note Mortgage Bonds and (2) together with the fair
value to the Company, as described in the certificates to be
delivered pursuant to this Section 1306(a), of all other Senior
Note Mortgage Bonds delivered to the Trustee since the
commencement of the then current calendar year, is equal to or
exceeds 10% of the principal amount of the Securities outstanding
at the date of delivery of such Senior Note Mortgage Bonds, then
the certificate required by this Section 1306(a) shall (1) be
delivered by an Expert who shall be independent of the Company
and satisfactory to the Trustee in its reasonable judgment and
(2) shall, in addition to the certifications described above,
state the fair value to the Company of all Senior Note Mortgage
Bonds delivered to the Trustee pursuant to Section 1301 hereof
since the commencement of the then current year as to which a
certificate was not delivered by an Expert independent of the
Company.

          (b)  If Senior Note Mortgage Bonds are delivered or

hereof, the Company shall simultaneously therewith deliver to the
Trustee a certificate of an Expert (1) stating that it is
familiar with the provisions of such Senior Note Mortgage Bonds
and of this Indenture, (2) stating the principal amount of such
Senior Note Mortgage Bonds so delivered, the stated interest rate

          SECTION 1307.  Further Assurances.

and execute and deliver such additional conveyances, assignments,
assurances, agreements, financing statements and instruments, as

confirm to the Trustee its security interest in the Senior Note
Mortgage Bonds and for maintaining, protecting and preserving
such security interest.

           SECTION 1308.  Exchange and Surrender of Senior Note 
                          Mortgage Bonds.

          At any time at the written direction of the Company,
the Trustee shall surrender to the Company all or part of the
Senior Note Mortgage Bonds in exchange for Senior Note Mortgage
Bonds equal in aggregate outstanding principal amounts to, in
different denominations than but of the same series and with all
other terms identical to, the Senior Note Mortgage Bonds so
surrendered to the Company. In addition, at any time a Security
shall cease to be entitled to any lien, benefit or security under
this Indenture pursuant to Section 404 hereof, the Trustee shall
surrender Senior Note Mortgage Bonds as provided in this Section
to the Company for cancellation. The Trustee shall, together with
such Senior Note Mortgage Bonds, deliver to the Company such
appropriate instruments of transfer or release as the Company may
reasonably request. Prior to the surrender required by this
paragraph, the Trustee shall receive from the Company the
following, and (subject to Section 601 hereof) shall be fully
protected in relying upon, (a) an Officers' Certificate stating
(i) the aggregate outstanding principal amount of the Senior Note
Mortgage Bonds of the series surrendered by the Trustee, after
giving effect to such surrender, (ii) the aggregate outstanding
principal amount of the related series of Securities, (iii) that
the surrender of the Senior Note Mortgage Bonds will not result
in any default under this Indenture, and (iv) that any Senior
Note Mortgage Bonds to be received in exchange for the Senior
Note Mortgage Bonds being surrendered comply with the provisions
of this Section 1308.

          The Company shall not be permitted to cause the
surrender or exchange of all or any part of a series of Senior
Note Mortgage Bonds contemplated in this Section 1308, if, after
such surrender or exchange, the aggregate outstanding principal
amount of the related series of Securities would exceed the
aggregate outstanding principal amount of such series of Senior
Note Mortgage Bonds held by the Trustee.  Any Senior Note
Mortgage Bonds received by the Company pursuant to this Section
1308 shall be delivered to the First Mortgage Trustee for
cancellation.

          SECTION 1309.  Terms of Senior Note Mortgage Bonds.

          Each series of Senior Note Mortgage Bonds delivered to
the Trustee pursuant to Section 1301 hereof shall have the same
stated rate or rates of interest (or interest calculated in the
same manner), Interest Payment Dates, Stated Maturity, and
redemption provisions, and shall be in the same aggregate
principal amount, as the related series of Securities being
issued.

          SECTION 1310.  Senior Note Mortgage Bonds as Security 
                         for Securities.

          Until the Release Date and subject to Article Four
hereof, Senior Note Mortgage Bonds delivered to the Trustee, for
the benefit of the Holders of the Securities, shall serve as
security for any and all obligations of the Company under the
Securities, including, but not limited to (1) the full and prompt
payment of the principal of such Securities when and as the same
shall become due and payable in accordance with the terms and
provisions of this Indenture or the Securities, either at the
Stated Maturity thereof, upon acceleration of the maturity
thereof or upon redemption, and (2) the full and prompt payment
of any interest on such Securities when and as the same shall
become due and payable in accordance with the terms and
provisions of this Indenture or the Securities.

          Notwithstanding anything in this Indenture to the
contrary, from and after the Release Date, the obligation of the
Company to make payment with respect to the principal of and
premium, if any, and interest on the Senior Note Mortgage Bonds
shall be deemed satisfied and discharged as provided in the
supplemental indenture or indentures to the First Mortgage
Indenture creating such Senior Note Mortgage Bonds and the Senior
Note Mortgage Bonds shall cease to secure in any manner
Securities theretofore or subsequently issued.  From and after
the Release Date, any conditions to the issuance of Securities
that refer or relate to Senior Note Mortgage Bonds or the First
Mortgage Indenture shall be inapplicable.  Following the Release
Date, the Company shall cause the First Mortgage Indenture to be
closed and the Company shall not issue any additional First
Mortgage Bonds or Senior Note Mortgage Bonds under the First
Mortgage Indenture.  Notice of the occurrence of the Release Date
shall be given by the Trustee to the Holders of the Securities in
the manner provided in Section 106 hereof not later than 30 days
after the Company notifies the Trustee of the occurrence of the
Release Date.

time of payment is legal tender for the payment of public and
private debts; provided, however, that at the option of the
Company payment of interest may be made by check mailed to the

Holders of the Securities of each series to be affected under the
Indenture at any time by the Company and the Trustee with the
consent of the Holders of not less than a majority in principal
amount of the Securities at the time Outstanding of all series to

provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such
series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the
Indenture and their consequences.  Any such consent or waiver by
the Holder of this Security shall be conclusive and binding upon
such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or
in exchange herefor or in lieu hereof, whether or not notation of
such consent or waiver is made upon this Security.

          No reference herein to the Indenture and no provision
of this Security or of the Indenture shall alter or impair the
obligation of the Company, which is absolute and unconditional,

respect to such series or its nominee only as provided in this
paragraph.  This Security shall be so exchangeable if (x) the
Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for such series or at any time ceases to
be a clearing agency registered as such under the Securities
Exchange Act of 1934, (y) the Company executes and delivers to
the Trustee an Officers' Certificate providing that this Security
shall be so exchangeable or (z) there shall have occurred and be
continuing an Event of Default with respect to the Securities of
such series.  Securities so issued in exchange for this Security
shall be of the same series, having the same interest rate, if
any, and maturity and having the same terms as this Security, in
authorized denominations and in the aggregate having the same
principal amount as this Security and registered in such names as
the Depositary for such Global Security shall direct.

          As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of a Security of the
series of which this Security is a part is registrable in the
Security Register, upon surrender of this Security for
registration of transfer at the office or agency of the Company
in any place where the principal of (and premium, if any) and
interest, if any, on this Security are payable, duly endorsed by,
or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his or her attorney duly
authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, of authorized denominations and
for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

          The Securities of the series of which this Security is
a part are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations
therein set forth, Securities of this series are exchangeable for
a like aggregate principal amount of Securities of this series
and of like tenor of a different authorized denomination, as
requested by the Holder surrendering the same.

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

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

          This Security shall be governed by and construed in

business of the Trustee or at such other office or agency of the Company as

issued in fully registered form without coupons, substantially in the form

Company by its President, a Vice President, its Secretary or an Assistant
Secretary may be so executed by the facsimile signature of such President,
Vice President, Secretary or Assistant Secretary, as the case may be, of
the Company or of any person or persons who shall have been such officer or

                           ARTICLE II

          REDEMPTION OF FIRST MORTGAGE BONDS, SERIES X

 SECTION 1.  (a) Upon notice being given of the redemption of all or part
of the Senior Notes in accordance with the Senior Note Indenture and such
Senior Notes becoming due and payable in accordance with such notice of
redemption, the Company shall redeem on the redemption date specified in
such notice a principal amount of bonds of Series X equal to the principal
amount of Senior Notes to be redeemed, at a redemption price equal to the
principal amount of such bonds of Series X to be redeemed, plus a premium
equal to the premium payable on the redemption of such Senior Notes, plus
accrued interest to such redemption date.

 (b) In the event the principal of all Senior Notes is declared due and
payable pursuant to Section 502 of the Senior Note Indenture, the bonds of
Series X shall be redeemable in whole upon receipt by the Trustee of a
written demand (hereinafter called a "Redemption Demand") from the Senior
Note Trustee stating that there has been such declaration, stating that it
is acting pursuant to the authorization granted by Section 502 of the
Senior Note Indenture, and demanding redemption of all bonds of Series X on
a date specified in such Redemption Demand (the "Demand Redemption Date"),
which date shall not be less than 10 days nor more than 35 days after the
date of the Redemption Demand.  The Trustee shall, within 3 days after
receiving such Redemption Demand,  mail a copy thereof to the Company
marked to indicate the date of its receipt by the Trustee.  Upon receipt by
the Company of such copy of a Redemption Demand, the bonds of Series X
shall be redeemed by the Company on the Demand Redemption Date, upon
surrender thereof by the Senior Note Trustee to the Trustee, at a
redemption price equal to the principal amount thereof, plus accrued
interest to the Demand Redemption Date.  If a Redemption Demand is
rescinded by the Senior Note Trustee by written notice to the Trustee prior
to the Demand Redemption Date, the Company shall not be obligated to redeem
the bonds of Series X on the Demand Redemption Date; but no such rescission
shall extend to or affect any subsequent acceleration of the Senior Notes
or impair any right consequent thereon.

 SECTION 2.  The Company covenants that, for so long as any bonds of
Series X are outstanding, it will take appropriate action so that the bonds
of Series X are not redeemed or purchased pursuant to any sinking fund or
related requirement provided for in the Original Indenture.

 SECTION 3.  The Company covenants and agrees that, prior to the Release
Date, it will not take any action (except as required by Article II,
Section 1(b) hereof) that would cause the outstanding principal amount of
the bonds of Series X to be less than the then outstanding principal amount
of the Senior Notes.

 SECTION 4.  Redemption of bonds of Series X shall be effected, without
further notice by the Company or the Trustee, by the payment by the Company
of the applicable redemption price specified in Article II, Section 1
hereof at the place specified for payment of the principal of and interest
on such bonds.
