                                        Assistant Secretary



                       PUBLIC SERVICE COMPANY OF OKLAHOMA
                                 March 30, 2004


            The Chairman outlined a proposed financing program through December
31, 2005 of the Company involving the issuance and sale, either at competitive
bidding, through a negotiated public offering with one or more agents or
underwriters or through private placement, of up to $200,000,000 (or its
equivalent in another currency or composite currency) aggregate principal amount
of debt securities comprised of unsecured promissory notes, in one or more new
series, each series to have a maturity of not more than 40 years ("Debt
Securities"). He then stated that, as an alternative to issuing Debt Securities,
the Company may issue one or more unsecured promissory notes ("AEP Notes") to
American Electric Power Company, Inc. ("AEP") in an aggregate principal amount
of up to $200,000,000. AEP Notes would be issued in compliance with the order of
the Oklahoma Corporation Commission and any applicable rules of the Securities
Exchange Commission under the Public Utility Holding Company Act of 1935.

            The Chairman explained that it was proposed that the proceeds to be
received in connection with the proposed sale of Debt Securities would be added
to the general funds of the Company and used to redeem directly or indirectly
long-term debt, to refund directly or indirectly preferred stock, to repay
short-term debt at or prior to maturity, to reimburse the Company's treasury for
expenditures incurred in connection with its construction program and for other
corporate purposes.

            Thereupon, on motion duly made and seconded, it was unanimously

                  RESOLVED, that the proposed financing program of this Company,
            as outlined at this meeting, be, and the same hereby is, in all
            respects ratified, confirmed and approved; and further

                  RESOLVED, that the proper officers of this Company be, and
            they hereby are, authorized to take all steps necessary, or in their
            opinion desirable, to carry out the financing program outlined at
            this meeting.

            The Chairman stated that the Company has executed and filed an
application with the Oklahoma State Corporation Commission seeking authorization
for the issuance of $200,000,000 of Debt Securities. He then stated that it may
be necessary to file one or more Registration Statements pursuant to the
applicable provisions of the Securities Act of 1933, as amended, and to register
or qualify the securities to be sold pursuant to such financing program under
the "blue sky" laws of various jurisdictions.

            Thereupon, on motion duly made and seconded, it was unanimously

                  RESOLVED, that with respect to the proposed financing program
            approved at this meeting, the actions taken by the officers of this
            Company in connection with the execution and filing on behalf of the
            Company of the necessary application with the Oklahoma Corporation
            Commission be, and they hereby are, ratified, confirmed and approved
            in all respects; and further

                  RESOLVED, that the proper officers of this Company be, and
            they hereby are, authorized to execute and file with the Securities
            and Exchange Commission ("SEC") on behalf of the Company one or more
            Registration Statements pursuant to the applicable provisions of the
            Securities Act of 1933, as amended; and further

                  RESOLVED, that it is desirable and in the best interest of the
            Company that the Debt Securities be qualified or registered for sale
            in various jurisdictions; that the Chairman of the Board, the
            President, any Vice President, the Treasurer or any Assistant
            Treasurer and the Secretary or an Assistant Secretary hereby are
            authorized to determine the jurisdictions in which appropriate
            action shall be taken to qualify or register for sale all or such
            part of the Debt Securities of the Company as said officers may deem
            advisable; that said officers are hereby authorized to perform on
            behalf of the Company any and all such acts as they may deem
            necessary or advisable in order to comply with the applicable laws
            of any such jurisdictions, and in connection therewith to execute
            and file all requisite papers and documents, including, but not
            limited to, applications, reports, surety bonds, irrevocable
            consents and appointments of attorneys for service of process; and
            the execution by such officers of any such paper or document or the
            doing by them of any act in connection with the foregoing matters
            shall conclusively establish their authority therefor from the
            Company and the approval and ratification by the Company of the
            papers and documents so executed and the action so taken; and
            further

                  RESOLVED, that the proper officers of this Company be, and
            they hereby are, authorized and directed to take any and all further
            action in connection therewith, including the execution and filing
            of such amendment or amendments, supplement or supplements and
            exhibit or exhibits thereto as the officers of this Company may deem
            necessary or desirable.

            The Chairman indicated to the meeting that it may be desirable that
the Debt Securities be listed on the New York Stock Exchange and in connection
with any such application, to register the Debt Securities under the Securities
Exchange Act of 1934, as amended.

            Thereupon, it was, on motion duly made and seconded, unanimously

                  RESOLVED, that the officers of this Company be, and they
            hereby are, authorized, in their discretion, to make one or more
            applications, on behalf of this Company, to the New York Stock
            Exchange for the listing of up to $200,000,000 aggregate principal
            amount of Debt Securities; and further

                  RESOLVED, that Susan Tomasky, Stephen P. Smith, Wendy G.
            Hargus and Armando A. Pena, or any one of them, be, and they hereby
            are, designated to appear before the New York Stock Exchange with
            full authority to make such changes in any such application or any
            agreements relating thereto as may be necessary or advisable to
            conform with the requirements for listing; and further

                  RESOLVED, that the proper officers be, and they hereby are,
            authorized to execute and file, on behalf of this Company, one or
            more applications for the registration of up to $200,000,000
            aggregate principal amount of Debt Securities with the Securities
            and Exchange Commission pursuant to the provisions of the Securities
            Exchange Act of 1934, as amended, in such form as the officers of
            this Company executing the same may determine; and further

                  RESOLVED, that the Chairman of the Board, the President, Susan
            Tomasky, Stephen P. Smith, Wendy G. Hargus and Armando A. Pena, the
            Secretary or an Assistant Secretary be, and each of them hereby is,
            authorized, in the event any said application for listing is made,
            to execute and deliver on behalf of this Company an indemnity
            agreement in such form, with such changes therein as the officers
            executing the same may approve, their execution to be conclusive
            evidence of such approval; and further

                  RESOLVED, that the Chairman of the Board, the President, any
            Vice President, the Treasurer or any Assistant Treasurer be, and
            each of them hereby is, authorized to take any other action and to
            execute any other documents that in their judgment may be necessary
            or desirable in connection with listing the Debt Securities on the
            New York Stock Exchange.

            The Chairman further stated that, in connection with the filing with
the SEC of one or more Registration Statements relating to the proposed issuance
and sale of up to $200,000,000 of Debt Securities, there was to be filed with
the SEC a Power of Attorney, dated March 30, 2004, executed by the officers and
directors of this Company appointing true and lawful attorneys to act in
connection with the filing of such Registration Statement(s) and any and all
amendments thereto.

            Thereupon, on motion duly made and seconded, the following preambles
and resolutions were unanimously adopted:

                  WHEREAS, the Company proposes to file with the SEC one or more
            Registration Statements for the registration pursuant to the
            applicable provisions of the Securities Act of 1933, as amended, of
            up to $200,000,000 aggregate principal amount of Debt Securities, in
            one or more new series, each series to have a maturity of not less
            than nine months and not more than 40 years; and

                  WHEREAS, in connection with said Registration Statement(s),
            there is to be filed with the SEC a Power of Attorney, dated March
            30, 2004, executed by certain of the officers and directors of this
            Company appointing Michael G. Morris, Susan Tomasky, Stephen P.
            Smith and Armando A. Pena, or any one of them, their true and lawful
            attorneys, with the powers and authority set forth in said Power of
            Attorney;

                  NOW, THEREFORE, BE IT

                  RESOLVED, that each and every one of said officers and
            directors be, and they hereby are, authorized to execute said Power
            of Attorney; and further

                  RESOLVED, that any and all action hereafter taken by any of
            said named attorneys under said Power of Attorney be, and the same
            hereby is, ratified and confirmed and that said attorneys shall have
            all the powers conferred upon them and each of them by said Power of
            Attorney; and further

                  RESOLVED, that said Registration Statement(s) and any
            amendments thereto, hereafter executed by any of said attorneys
            under said Power of Attorney be, and the same hereby are, ratified
            and confirmed as legally binding upon this Company to the same
            extent as if the same were executed by each said officer and
            director of this Company personally and not by any of said
            attorneys.

            The Chairman advised the meeting that it was proposed to designate
independent counsel for the successful bidder or bidders and/or agents of the
Company for the new series of Debt Securities proposed to be issued and sold in
connection with the proposed financing program of the Company.

            Thereupon, on motion duly made and seconded, it was unanimously

                  RESOLVED, that Dewey Ballantine LLP be, and said firm hereby
            is, designated as independent counsel for the successful bidder or
            bidders and/or agents of the Company for the new series of Debt
            Securities of this Company proposed to be issued and sold in
            connection with the proposed financing program of this Company.

            The Chairman stated that it may be desirable to enter into hedge
agreements, such as a forward starting swap, treasury lock agreement, treasury
put option or interest rate collar agreement ("Hedge Agreement") to protect
against future interest rate movements in connection with the issuance of the
Debt Securities. He recommended that the Board authorize the appropriate
officers of the Company to enter into a Hedge Agreement, provided that the
amount covered by such Agreement would not exceed the principal amount of Debt
Securities the Company anticipates offering.

            Thereupon, it was, on motion duly made and seconded, unanimously

                  RESOLVED, that the Chairman of the Board, the President, any
            Vice President, the Treasurer or any Assistant Treasurer of this
            Company be, and each of them hereby is, authorized to execute and
            deliver in the name and on behalf of this Company, a Hedge Agreement
            in such form as shall be approved by the officer executing the same,
            such execution to be conclusive evidence of such approval, provided
            that the amount covered by such Agreement would not exceed the
            principal amount of Debt Securities the Company anticipates
            offering; and further

                  RESOLVED, that the proper officers of the Company be, and they
            hereby are, authorized to execute and deliver such other documents
            and instruments, and to do such other acts and things, that in their
            judgment may be necessary or desirable in connection with the
            transactions authorized in the foregoing resolutions.

            The Chairman stated that it may be desirable to enter into one or
more interest rate management agreements, such as interest rate swaps, caps,
collars, floors, options, or hedging products such as forwards or futures, or
similar products ("Interest Rate Management Agreements"), in each case to manage
and minimize interest costs. The transactions will be for a fixed period, stated
principal amount and for underlying fixed or variable obligations of the
Company. He recommended that the Board authorize the appropriate officers of the
Company to enter into one or more Interest Rate Management Agreements, provided
that any the aggregate notional amount of all Interest Rate Management
Agreements will not exceed 25% of the Company's total existing debt obligations
and such other conditions that may be imposed by any regulatory body.

            Thereupon, it was, on motion duly made and seconded, unanimously

                  RESOLVED, that the Chairman of the Board, the President, any
            Vice President, the Treasurer or any Assistant Treasurer of this
            Company be, and each of them hereby is, authorized to execute and
            deliver in the name and on behalf of this Company, one or more
            Interest Rate Management Agreements in such form as shall be
            approved by the officer executing the same, such execution to be
            conclusive evidence of such approval, provided that any the
            aggregate notional amount of all Interest Rate Management Agreements
            will not exceed 25% of the Company's total existing debt obligations
            and such other conditions that may be imposed by any regulatory
            body; and further

                  RESOLVED, that the proper officers of the Company be, and they
            hereby are, authorized to execute and deliver such other documents
            and instruments, and to do such other acts and things, that in their
            judgment may be necessary or desirable in connection with the
            transactions authorized in the foregoing resolutions.

            The Chairman explained that, with respect to the issuance of up to
$200,000,000 of Debt Securities through one or more agents under a medium term
note program, the Company could enter into a Selling Agency Agreement. He
recommended that the Board authorize the appropriate officers of the Company to
enter into such Selling Agency Agreement with securities dealers yet to be
determined.

            Thereupon, upon motion duly made and seconded, it was unanimously

                  RESOLVED, that the Chairman of the Board, the President, any
            Vice President, the Treasurer or any Assistant Treasurer of this
            Company be, and each of them hereby is, authorized to execute and
            deliver in the name and on behalf of this Company, a Selling Agency
            Agreement with such securities dealers in such form as shall be
            approved by the officer executing the same, such execution to be
            conclusive evidence of such approval; and further

                  RESOLVED, that the proper officers of the Company be, and they
            hereby are, authorized to execute and deliver such other documents
            and instruments, and to do such other acts and things, that in their
            judgment may be necessary or desirable in connection with the
            transactions authorized in the foregoing resolutions.

            The Chairman next explained that the Company could also enter into
an Underwriting Agreement ("Underwriting Agreement") with certain underwriters,
under which the underwriters may purchase up to $200,000,000 aggregate principal
amount of Debt Securities. He recommended that the Board authorize the
appropriate officers of the Company to enter into an Underwriting Agreement and
determine the purchase price of the Debt Securities, provided that the price
shall not be less than 95% (including compensation to the underwriters) of the
aggregate principal amount of the Debt Securities.

            Thereupon, it was, on motion duly made and seconded, unanimously

                  RESOLVED, that the Chairman of the Board, the President, any
            Vice President, the Treasurer or any Assistant Treasurer of this
            Company be, and each of them hereby is, authorized to execute and
            deliver in the name and on behalf of this Company, an Underwriting
            Agreement in such form as shall be approved by the officer executing
            the same, such execution to be conclusive evidence of such approval,
            provided that the purchase price of the Debt Securities shall not be
            less than 95% (including compensation to the underwriters) of the
            aggregate principal amount of the Debt Securities; and further

                  RESOLVED, that the proper officers of the Company be, and they
            hereby are, authorized to execute and deliver such other documents
            and instruments, and to do such other acts and things, that in their
            judgment may be necessary or desirable in connection with the
            transactions authorized in the foregoing resolutions.

            The Chairman explained that the Company may issue and sell unsecured
notes ("Notes"), pursuant to a Selling Agency Agreement, an Underwriting
Agreement or other Agreement. He further noted that, in order to enable the
Company to perform its obligations under the Selling Agency Agreement or the
Underwriting Agreement approved at this meeting providing for the sale of up to
$200,000,000 aggregate principal amount of the Notes, it was necessary that the
Board authorize the execution and delivery of one or more Company Orders or
Supplemental Indentures to the Indenture, dated as of November 1, 2000, between
the Company and The Bank of New York (the "Indenture"), in such form as shall be
approved by the officer executing the same, such execution to be conclusive
evidence of such approval. The terms of each series of Notes will be established
under a Company Order or a Supplemental Indenture. The interest rate, maturity
and certain other terms have not yet been determined. The Chairman recommended
that the Board authorize the appropriate officers of the Company to determine
the financial terms and conditions of the Notes, including, without limitation,
(i) the principal amount of the Notes to be sold in each offering; (ii) the
interest or method of determining the interest on the Notes; (iii) the maturity
(which shall not exceed 40 years from the date of issuance) and redemption
provisions of the Notes; and (iv) such other terms and conditions as are
contemplated or permitted by the Indenture, a Company Order or a Supplemental
Indenture. Any fixed interest rate applicable to the Notes would not exceed by
more than 350 basis points the yield to maturity of United States Treasury
obligations of comparable maturity at the time of pricing of the Notes. Any
initial fluctuating interest rate applicable to the Notes would not exceed 6%.

            Thereupon, it was, on motion duly made and seconded, unanimously

                  RESOLVED, that the Chairman of the Board, the President, any
            Vice President, the Treasurer or any Assistant Treasurer and the
            Secretary or any Assistant Secretary be, and they hereby are,
            authorized to create up to $200,000,000 aggregate principal amount
            of Notes to be issued under the Indenture and one or more
            Supplemental Indentures or Company Orders, in such form as shall be
            approved by the officer executing the same, such execution to be
            conclusive evidence of such approval, and with such financial terms
            and conditions as determined by appropriate officers of this
            Company, pursuant to the Indenture and one or more Supplemental
            Indentures or Company Orders, and with either a fixed rate of
            interest which shall not exceed by more than 350 basis points the
            yield to maturity on United States Treasury obligations of
            comparable maturity at the time of pricing of the Notes or at an
            initial fluctuating rate of interest which at the time of pricing
            would not exceed 6%, or at a combination of such described fixed or
            fluctuating rates, and to specify the maturity, redemption or tender
            provisions and other terms, at the time of issuance thereof with the
            maturity not to exceed 40 years; and further

                  RESOLVED, that the Chairman of the Board, the President, any
            Vice President, the Treasurer or any Assistant Treasurer and the
            Secretary or any Assistant Secretary be, and they hereby are,
            authorized and directed to execute and deliver, on behalf of this
            Company, one or more Supplemental Indentures or Company Orders,
            specifying the designation, terms, redemption provisions and other
            provisions of the Notes and providing for the creation of each
            series of Notes, in such form as shall be approved by the officer
            executing the same, such execution to be conclusive evidence of such
            approval; that The Bank of New York is hereby requested to join in
            the execution of any Supplemental Indenture or Company Order, as
            Trustee; and further

                  RESOLVED, that the Chairman of the Board, the President, any
            Vice President, the Treasurer or any Assistant Treasurer be, and
            they hereby are, authorized and directed to execute and deliver, on
            behalf of this Company, to the extent not determined in a
            Supplemental Indenture or Company Order, a certificate requesting
            the authentication and delivery of any such Notes and establishing
            the terms of any tranche of such series or specifying procedures for
            doing so in accordance with the procedures established in the
            Indenture; and further

                  RESOLVED, that the Chairman of the Board, the President, any
            Vice President or the Treasurer and the Secretary or any Assistant
            Secretary of this Company be, and they hereby are, authorized and
            directed to execute in accordance with the provisions of the
            Indenture (the signatures of such officers to be effected either
            manually or by facsimile, in which case such facsimile is hereby
            adopted as the signature of such officer thereon), and to deliver to
            The Bank of New York, as Trustee under the Indenture, the Notes in
            the aggregate principal amount of up to $200,000,000 as definitive
            fully registered bonds without coupons in such denominations as may
            be permitted under the Indenture; and further

                  RESOLVED, that if any authorized officer of this Company who
            signs, or whose facsimile signature appears upon, any of the Notes
            ceases to be such an officer prior to their issuance, the Notes so
            signed or bearing such facsimile signature shall nevertheless be
            valid; and further

                  RESOLVED, that, subject as aforesaid, The Bank of New York, as

            The Chairman further stated that it would be desirable to authorize
the proper officers of the Company, on behalf of the Company, to issue one or
more unsecured promissory notes to American Electric Power Company, Inc. ("AEP")
in an aggregate principal amount of up to $200,000,000 on such terms as are
consistent with (i) its financing authority granted by the Oklahoma Corporation
Commission and (ii) any applicable rules of the Securities Exchange Commission
under the Public Utility Holding Company Act of 1935 and regulations thereunder
("PUHCA").

            Thereupon, upon motion duly made and seconded, it was unanimously

                  RESOLVED, that the Chairman of the Board, the President, any
            Vice President, the Treasurer or any Assistant Treasurer of this
            Company be, and each of them hereby is, authorized, in the name and
            on behalf of this Company, to borrow from AEP up to $200,000,000,
            upon such terms as are consistent with (i) the financing authority
            granted by the Oklahoma Corporation Commission and (ii) any
            applicable rules of the Securities Exchange Commission under PUHCA.

            The Chairman also reminded the Board that on behalf of the Company
the Oklahoma Development Finance Authority, a public trust and agency of the
State of Oklahoma (the "Authority"), had issued a series of Pollution Control
Revenue Refunding Bonds (Public Service Company of Oklahoma Project) Series 1999
(the "Bonds"), in the aggregate principal amount of $33,700,000 pursuant to an
Indenture of Trust, dated as of June 15, 1999, between the Authority and The
Bank of Oklahoma, N.A., as Trustee (the "Trustee"), as supplemented and amended
(the "Indenture"), for the purpose of refunding certain pollution control
revenue bonds issued to finance a portion of the costs of acquiring,
constructing, installing and equipping certain pollution control facilities at
the Company's Northeastern Generating Station near Oologah, Oklahoma. The
Company is considering the remarketing of the Bonds or the issuance of new bonds
to refund the Bonds (the "Refunding Bonds"). In connection with the refunding,
the officers of the Company would enter into a new Installment Payment Agreement
(the "Agreement") relating to the Refunding Bonds.

            The Chairman advised the Board that the Company would enter into a
Contract of Purchase (the "Contract") with one or more underwriters
(collectively, the "Purchaser"), providing for the purchase of the Bonds or the
Refunding Bonds by the Purchaser at a price of 100% of the principal amount
thereof, plus accrued interest. The Contract will further provide that as
compensation for the services of the Purchaser in purchasing and remarketing the
Bonds or the Refunding Bonds, the Company will pay compensation not to exceed 3%
of the issuance, plus reasonable expenses, to the Purchaser.

            The Chairman further stated that the Company proposes to enter into
an inducement letter (the "Letter") with the Authority and the purchaser named
therein in connection with the issuance of the Bonds or the Refunding Bonds.

            Thereupon after full and complete discussion, on motion duly made
and seconded, it was unanimously

                  RESOLVED, that the proper officers of this Company be, and
            they hereby are, authorized and directed to enter into the Contract,
            the Agreement and the Letter in such form as may be acceptable to
            them, provided that the initial interest rate on the Bonds or the
            Refunding Bonds not exceed 9% and the compensation paid to the
            Purchaser not exceed 3% of the issuance; and further

                  RESOLVED, that the proper officers of this Company be, and
            they hereby are, authorized and directed to take such further action
            and do all other things as they or any one of them shall deem
            necessary or desirable in connection with the Agreement, the
            Contract and the Letter or otherwise in connection with the
            adjustment of the interest rate on the Bonds or the remarketing of
            the Bonds or the purchase of the Refunding Bonds by the Purchaser.

            The Chairman then stated that one or more insurance companies may
insure the payment of principal and interest on certain types of Debt
Securities, Bonds or Refunding Bonds as such payments become due pursuant to a
financial guaranty insurance or other policy or agreement ("Insurance Policy").
In this connection, the Company proposes to enter into one or more Insurance
Agreements, in such form as shall be approved by the officer executing the same,
such execution to be conclusive evidence of such approval.

            Thereupon, after discussion, on motion duly made and seconded, it
was unanimously

                  RESOLVED, that in order to enhance the credit of one or more
            series of Debt Securities, Bonds or Refunding Bonds, the proper
            officers of the Company be, and they hereby are, authorized to
            execute and deliver on behalf of the Company one or more Insurance
            Agreements with an insurance company or other institution of their
            choice, in such form as shall be approved by the officer executing
            the same, such execution to be conclusive evidence of such approval;
            and further

                  RESOLVED, that the proper officers of the Company be, and they
            hereby are, authorized on behalf of the Company to take such further
            action and do all other things that any one of them shall deem
            necessary or appropriate in connection with, the Insurance Policy
            and the Insurance Agreement.
