principal or interest, or the creation of a lien on the mortgaged and
pledged property ranking prior to or on a parity with the lien of the
Mortgage or the deprivation of the owner hereof of a lien upon such property
without the consent of the owner hereof, except that the owners of not less
than seventy-five percent (75%) in principal amount of the bonds at any time
outstanding under the Mortgage (including a like percent of the principal
amount of the bonds of the 2030 Series, if any interest payment on bonds of
the 2030 Series is to be affected) may consent on behalf of the owners of
all bonds at any time outstanding to the postponement of any interest
payment for a period not exceeding three years from its due date.

fixed for redemption), discounted (for purposes of determining such present
values) to the date fixed for redemption on a semiannual basis (assuming a

case, accrued interest thereon to the date fixed for redemption without
premium.  Except as set forth above, the bonds of the 2030 Series are not
redeemable prior to September 15, 2030.

     The notice of redemption of bonds of the 2030 Series shall be given by
mailing a copy thereof to each registered owner, directed to his registered
address not less than thirty nor more than ninety days prior to the date
fixed for redemption, all as provided in, and subject to the applicable
provisions of, the Mortgage.

     The principal hereof may be declared or may become due on the
conditions, in the manner, and at the time set forth in the Mortgage, upon
the occurrence of a completed default as in the Mortgage provided.

     At the option of the registered owner, any bonds of the 2030 Series,
upon surrender thereof at the office or agency of the Company in the Borough
of Manhattan, The City of New York, or in the City of St. Louis, State of
Missouri, together with a written instrument of transfer in form approved by
the Company duly executed by the registered owner or his duly authorized
attorney, shall, subject to the provisions of Section 2.05 of the Original
Indenture, be exchangeable for a like aggregate amount of fully registered

registered owner hereof in person, or by his duly authorized attorney, at
the office or agency of the Company in the Borough of Manhattan, The City of
New York, or in the City of St. Louis, upon surrender and cancellation of

executed, and upon payment, if the Company shall require it, of the transfer
charges prescribed in the Mortgage, and thereupon, a new fully registered
bond of the same series for a like principal amount will be issued to the
transferee in exchange herefor as provided in the Mortgage.  The Company and
the Trustee may deem and treat the person in whose name this bond is
registered as the absolute owner hereof for the purpose of receiving payment
and for all other purposes.

     No recourse shall be had for the payment of the principal of or of
interest on this bond against any incorporator or any past, present or
future subscriber to the capital stock, stockholder, officer or director of
the Company or of any predecessor or successor corporation, as such, either
directly or through the Company or any predecessor or successor corporation,
under any rule of law, statute or constitution or by the enforcement of any

stockholders, officers and directors, as such, being released by the owner
hereof by the acceptance of this bond and being likewise waived and released
by the terms of the Mortgage.

                 REDEMPTION OF BONDS OF THE 2030 SERIES

     SECTION 3.1.   Bonds of the 2030 Series shall be redeemable, in whole
or in part, at 100% of the principal amount thereof, together with accrued
interest to the date fixed for redemption at any time before maturity by the
application of cash deposited with the Trustee as the result of the
operation of the Maintenance and Improvement Fund provided for in Section
9.07 of the Original Indenture or in Section 4.1 hereof, or pursuant to the
provisions of paragraph (B) of Section 13.06 of the Original Indenture.

     SECTION 3.2.   Bonds of the 2030 Series shall also be redeemable, at
the option of the Company, in whole at any time or in part from time to
time, prior to maturity, at a redemption price equal to the greater of: (A)
100% of the principal amount of the bonds of the 2030 Series being redeemed;
and (B) as determined by the Independent Investment Banker, as hereinafter
defined, the sum of the present values of the remaining scheduled payments
of principal of and interest on the bonds of the 2030 Series being redeemed
(excluding the portion of any such interest accrued to the date fixed for
redemption), discounted (for purposes of determining such present values) to
the date fixed for redemption on a semi-annual basis (assuming a 360-day
year of twelve 30-day months) at the Adjusted Treasury Rate, as hereinafter
defined, plus .25% plus, in each case, accrued interest thereon to the date
fixed for redemption without premium.

     For purposes of this Section 3.2:

     "Adjusted Treasury Rate" means, with respect to any date fixed for
redemption:

          (a) the yield, under the heading which represents the average for
the immediately preceding week, appearing in the most recently published
statistical release designated "H.15(519)" or any successor publication
which is published weekly by the Board of Governors of the Federal Reserve
System and which reports yields on actively traded United States Treasury
securities adjusted to constant maturity under the caption "Treasury
Constant Maturities," for the maturity corresponding to the Comparable
Treasury Issue (if no maturity is within three months before or after the
remaining term of the bonds of the 2030 Series, yields for the two published
maturities most closely corresponding to the Comparable Treasury Issue shall
be determined and the Adjusted Treasury Rate shall be interpolated or
extrapolated from such yields on a straight line basis, rounding to the
nearest month); or

          (b) if such release (or any successor release) is not published
during the week preceding the calculation date or does not contain such
yields, the rate per annum equal to the semiannual equivalent yield to
maturity of the Comparable Treasury Issue, calculated using a price for the
Comparable Treasury Issue (expressed as a percentage of its principal
amount) equal to the Comparable Treasury Price for such date fixed for
redemption.

The Adjusted Treasury Rate shall be calculated on the third Business Day
preceding the date fixed for redemption.

                                    20
<PAGE>
<PAGE>
     "Business Day" means any day other than a Saturday or a Sunday or a day
on which banking institutions in The City of New York are authorized or
required by law or executive order to remain closed or a day on which the
corporate trust office of the Trustee is closed for business.

     "Comparable Treasury Issue" means the United States Treasury security
selected by the Independent Investment Banker as having a maturity
comparable to the remaining term of the bonds of the 2030 Series that would
be utilized at the time of selection and in accordance with customary
financial practice, in pricing new issues of corporate debt securities of
comparable maturity to the remaining term of the bonds of the 2030 Series.

     "Comparable Treasury Price" means, with respect to any date fixed for
redemption, (a) the average of five Reference Treasury Dealer Quotations for
such date fixed for redemption after excluding the highest and the lowest
such Reference Treasury Dealer Quotations or (b) if the Independent
Investment Banker obtains fewer than five such Reference Treasury Dealer
Quotations, the average of all such Reference Treasury Dealer Quotations.

     "Independent Investment Banker" means A.G. Edwards & Sons, Inc. or, if
such firm is unwilling or unable to select the Comparable Treasury Issue, an
independent investment banking institution of national standing appointed by
the Company.

     "Reference Treasury Dealer" means a primary U. S. Government securities
dealer selected by the Independent Investment Banker after consultation with
the Company.

     "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any date fixed for redemption, the average, as
determined by the Independent Investment Banker, of the bid and asked prices
for the Comparable Treasury Issue (expressed in each case as a percentage of
its principal amount) quoted in writing to the Independent Investment Banker
by such Reference Treasury Dealer at 5:00 p.m. on the third Business Day
preceding such date fixed for redemption.

     SECTION 3.3.  Article XII of the Original Indenture is and shall be
applicable to any redemption of bonds of the 2030 Series.  The notice of
intention to redeem provided for in Section 12.02 of the Original Indenture
need not be published with respect to bonds of the 2030 Series but shall be
given by mailing a copy thereof to each registered owner thereof, directed
to his registered address, not less than thirty (30) nor more than ninety
(90) days prior to the date fixed for redemption.

                                ARTICLE IV
                   PARTICULAR COVENANTS OF THE COMPANY

     SECTION 4.1.  So long as any bonds of the 2030 Series are outstanding,
all covenants and provisions of Section 9.07 of the Original Indenture which
(under the terms of the Original Indenture and without regard to any
provision of any supplemental indenture heretofore or hereafter executed)
expired when all bonds of the 3 1/2% Series due 1965 ceased to be
outstanding, shall continue in force and effect; provided, however, that the
provisions of said Section 9.07 with

                                    21
<PAGE>
<PAGE>
reference to computing the Maintenance and Improvement Fund on the basis of
15% of the gross operating revenue of the Company (which had ceased to be
applicable prior to the retirement of the 3 1/2% Series due 1965) shall
remain inapplicable, and the provisions for such computation on the basis of
2 3/4% of the average amount of the gross property account of the Company
shall continue to apply, so long as any bonds of the 2030 Series are
outstanding.

     SECTION 4.2.  So long as any of the bonds of the 2030 Series are
outstanding, the Company will not (a) declare any dividends (other than
dividends in common stock) on any common stock, or order the making of any
distribution on any shares of common stock or to owners of common stock or
(b) purchase, redeem or otherwise acquire or retire for value any shares of
common stock, if the aggregate net amount of such declarations,
distributions so ordered, purchases, redemptions, acquisitions and
retirements after September 30, 1953, would exceed the sum of (a) the Net
Income Available for Common Stock for the period beginning October 1, 1953,
and ending with the last day of the calendar quarter immediately preceding
the calendar quarter in which such dividend is declared, distribution
ordered, or purchase, redemption, acquisition or retirement made, plus (b)
Eight Million Dollars ($8,000,000).

     The aggregate net amount of the declarations, distributions ordered,
purchases, redemptions, acquisitions and retirements referred to in the
first paragraph of this Section 4.2 shall be determined by deducting from
the aggregate amount thereof the total amount of cash payments received by
the Company after September 30, 1953, for any shares of common stock sold by
the Company after September 30, 1953.

     Net Income Available for Common Stock, for the purpose of this Section
4.2, for any period, means (1) the net income of the Company for such period
computed according to the applicable system of accounts prescribed by the
Public Service Commission of Missouri and any applicable orders of said
Commission and (to the extent not prescribed by such system of accounts or
orders) according to generally accepted accounting principles, less (2) an
amount equal to the dividends accrued (whether or not declared or paid)
during such period on any and all classes of stock having preference over
the common stock as to assets or dividends.

     For the purposes of the last preceding paragraph of this Section 4.2,
the term "Public Service Commission of Missouri" shall also apply, and be
deemed to refer, to any regulatory body which may (1) succeed said
Commission with respect to jurisdiction over the accounting of the Company,
or (2) supersede said Commission with respect to such jurisdiction, or (3)
have such jurisdiction over phases of the Company's business or parts of its
property over which said Commission shall not have jurisdiction.

     SECTION 4.3.  So long as any bonds of the 2030 Series are outstanding,
the Company shall not be entitled to have authenticated and delivered any
bonds pursuant to Article VI, Article VII or Article VIII of the Original
Indenture, except bonds which may be authenticated and delivered under
Article VII of the Original Indenture, without the receipt by the Trustee of
a net earnings certificate showing the net earnings to be as required by
Section 6.05 of the Original Indenture, unless (in addition to all other
requirements for the authentication and delivery of such bonds):

                                    22
<PAGE>
<PAGE>
          (a)  net earnings of the Company after provision for depreciation,
depletion and amortization of property, for any 12 consecutive calendar
months within the 15 calendar months immediately preceding the date on which
such additional bonds are to be issued, shall have been not less than 2 1/4
times the amount of the total annual interest charges upon the funded debt
of the Company to be outstanding immediately after the issue of such
additional bonds; and

          (b)  the Trustee shall have received a certificate made, signed
and verified by the same persons (including an independent public accountant
where required) as would be required if such certificate were a net earnings
certificate under the Original Indenture, showing the net earnings of the
Company to be as required by the foregoing clause (a) of this Section 4.3.
Such certificate shall show the net earnings and total annual interest
charges referred to in said clause (a).

     For the purposes of this Section 4.3, "funded debt" shall mean all
indebtedness created or assumed by the Company maturing one year or more
after the date of the creation or assumption thereof.

     For the purposes of this Section 4.3, net earnings of the Company after
provision for depreciation, depletion and amortization of property shall
mean the total operating revenue and other income (net) of the Company less
operating expenses (including provision for depreciation, depletion and
amortization of property) and less taxes (excluding income and excess
profits taxes or other taxes which are imposed on or measured by income).
In the determination of net earnings of the Company the following additional
requirements shall be applicable:

          (i)  No profits or losses from the sale or abandonment of capital
assets or change in value of securities or other investments shall be taken
into account in making such computations;

          (ii) In case the Company shall have sold any property for a
consideration in excess of $5,000,000, within or after the particular period
for which the calculation is made, then, in computing the net earnings of
the Company so available, the net earnings or net losses of such property
for the whole of such period shall be excluded to the extent practicable on
the basis of actual earnings and expenses of such property or on the basis
of such estimates of the earnings and expenses of such property as the
signers of a Treasurer's certificate filed with the Trustee shall deem
proper;

          (iii)  In case the Company shall, within or after the particular
period for which the calculation is made, have acquired (by purchase,
merger, consolidation or otherwise) any property which within six months
prior to the date of acquisition thereof by the Company has been used or
operated by a person or persons other than the Company in a business similar
to that in which it has been or is to be used or operated by the Company,
then in computing the net earnings of the Company so available for such
purposes there shall be included, to the extent that they may not have been
otherwise included, the net earnings or net losses of the property so
acquired for the whole of such period to the extent practicable on the basis
of actual earnings and expenses of such property or on the basis of such
estimates of the earnings and expenses of such property as the signers of a
Treasurer's certificate filed with the Trustee shall deem proper.  The net
earnings or net losses of such property for the period preceding such
acquisition shall in such case be ascertained

                                    23
<PAGE>
<PAGE>
and computed as provided in this clause (iii) as if such acquired property
had been owned by the Company during the whole of such period;

          (iv)  The "net earnings of property" referred to in clauses (ii)
and (iii) of this Section 4.3 shall mean the net earnings of such property
computed in the manner provided in this definition for the computation of
net earnings of the Company available for the pertinent purposes.

     All accounting determinations required by this Section 4.3 shall
(except to the extent, if any, to which the preceding provisions of this
Section 4.3 may conflict with this provision) be made according to the
applicable system of accounts prescribed by the Public Service Commission of
Missouri and any applicable orders of said Commission and (to the extent not
prescribed by such system of accounts or orders) according to generally
accepted accounting principles.

     For the purposes of this Section 4.3, the term "Public Service
Commission of Missouri" shall be applicable as provided in Section 4.2 of
this Article IV.

     SECTION 4.4.  So long as any bonds of the 2030 Series are outstanding,
in order that any interest payment on the bonds of the 2030 Series may be
postponed pursuant to clause (2) of Section 20.07 of the Original Indenture,
there shall be required, in addition to all other prerequisites to such
postponement provided in the Original Indenture, the consent of the owners
of not less than seventy-five percent (75%) in principal amount of bonds of
the 2030 Series at the time outstanding, such consent to be given at the
same time as and in the same manner as the consent of the owners of other
bonds required by said clause (2) of Section 20.07 of the Original
Indenture.

                                ARTICLE V
                              MISCELLANEOUS

     SECTION 5.1.  In any case where the date of maturity of interest on or
principal of bonds of the 2030 Series or the date fixed for redemption of
any such bonds shall be in the Borough of Manhattan, The City of New York,
or in the City of St. Louis, State of Missouri, a legal holiday or a day on
which banking institutions are authorized by law to close, then payment of
interest or principal need not be made on such date, but may be made on the
next succeeding date not in The City of New York, or in the City of St.
Louis, a legal holiday or a day on which banking institutions are authorized
by law to close, with the same force and effect as if made on the date of
maturity or the date fixed for redemption, and no interest shall accrue for
the period after such date.

     SECTION 5.2.  If and to the extent that any provision hereof, or any
other provision of the Mortgage, limits, qualifies, or conflicts with
another provision included in the Mortgage which is required to be included
in the Mortgage by any of Sections 310 to 317, inclusive, of the Trust
Indenture Act of 1939, as amended by the Trust Indenture Reform Act of 1990,
through operation of Section 318(c) thereof, such required provisions shall
control.

     SECTION 5.3.  The Trustee hereby accepts the trust hereby declared and
provided and agrees to perform the same upon the terms and conditions in the
Original Indenture and in this Twenty-Fifth Supplemental Indenture set
forth.

simultaneously executed in any number of counterparts, each of which, when
so executed, shall be deemed to be an original; such counterparts shall
together constitute but one and the same instrument.

2000, the actual dates of execution by the Company and by the Trustee are as
